ZTC-203-10X-o2CFS TetraCAM Documentation Camera System for Forensic Science by Zarbeco

The TetraCam is a portable digital microscope and macro imaging system. The 1-40x magnification system is quick to setup and easy to use. It will image from a full page down to the individual specks of laser printer toner using the 2.0 megapixel camera, which has four times the resolution of a conventional video camera. There is a large working distance with plenty of room to position your samples. The stand allows adjustment of height and camera angle while the camera's quick release mount provides for hand-held use.

The TetraCam includes a range of lighting systems. Use the fluorescent lamp for large area imaging. The supplemental LED light adds brightness at high magnifications and also provides oblique illumination to look at surface features like paper fibers and signature indentation.

The included Video ToolBox PRO software provides an easy-to-use interface for image and movie capture, labeling, annotation and advanced measurement tools. It lets you place time stamps, grids and reticles over the live image; you can even draw directly on the live image. The camera also includes DirectShow and TWAIN drivers so it is compatible with most editing programs and image databases.

Features

• View straight down or at an angle
• High-resolution 2.0 megapixel camera (5.0 megapixel camera optional)
• Video ToolBox PRO Software to capture, record, annotate, measure (Video ToolBox Premier Optional)

ZD22-701 ZD 22 Fixed Gas Transmitter with Oxygen (O2) Sensor, 0 - 25% vol. Range, No Display / 4-20 mA by GfG

Superior technology

The ZD 22 Transmitter is specifically designed for long-term monitoring of oxygen concentrations. The integrated amperometric oxygen sensor is based on an electrochemical oxygen pumping cell made of zirconium dioxide. It is characterized by its robustness, a very high life expectancy and its outstanding long-term stability. The integrated thermostatic control of the sensor element achieves accurate measuring results in the entire temperature range, regardless of the operating temperature. It can also be permanently used in environments with high concentrations of CO2 or in dry atmosphere. Special equipment is available to protect the transmitter when used in harsh environments.

Signal processing

The protective casing (IP 54) of the ZD 22 Transmitter contains the complete signal processing electronics and the failsafe routing of the measurement signal for the measuring computer, with extensive self-monitoring. The embedded software linearises the measuring signal and compensates for the effects of temperature. As a result, correct readings are transmitted even with weather related fluctuations in temperature. In addition, the transmitter can be connected to a gas measurement computer for the option of transmitting service, maintenance, and error messages.

Universal signal transmission

The ZD 22 Transmitter transmits the signals either using an analog (0.2 1mA / 4-20 mA) current interface or a digital (RS485) Modbus interface. This permits the universal use of the trasmitters in combination with GfG gas measurement computers and thus connection to a safety system, so that you and your systems will benefit from the best possible protection.

There are a variety of applications for the ZD 22 in regard to sensors, status LEDs and optional analog or digital interface, "Zero" key to calibrate the zero point, test socket and a potentiometer for the calibration of the sensor.

Weather protection

A weatherproof housing not only protects transmitters against exposure to wind and weather, but also against contamination and excessive temperatures caused by direct sunlight.

Optional colored graphic display

The clear graphic display of the ZD 22 is self explanatory and allows you to read the current status and other important information with ease. The display enables you to navigate effortlessly through the unit s concise menu and to change settings or even calibrate, depending on your user authorization. In the event of an alarm the display changes color from green to red. Two LEDs indicate the status.

Operation buttons

The buttons on the transmitter allow the unit to be calibrated and settings to be adjusted through the menu as needed.

Calibration adapter

In order to perform a calibration, a calibration adapter is used on the transmitter, which ensures a uniform and secure supply of gas.

Easy and convenient service

GfG offers full after-the-sale commissioning and field service support.

• Long service life of the sensors
• Extremely fast response time: t90 < 5 sec.
• Reduced pressure, humidity, or temperature influence
• No damage due to CO₂
• Cost effective single-man adjustment
• Affordable operation costs

The ZD 22 Transmitter is specifically designed for long-term monitoring of oxygen concentrations. The integrated amperometric oxygen sensor is based on an electrochemical oxygen pumping cell made of zirconium dioxide. It is characterized by its robustness, a very high life expectancy and its outstanding long-term stability. The integrated thermostatic control of the sensor element achieves accurate measuring results in the entire temperature range, regardless of the operating temperature. It can also be permanently used in environments with high concentrations of CO2 or in dry atmosphere. Special equipment is available to protect the transmitter when used in harsh environments.

Signal processing

The protective casing (IP 54) of the ZD 22 Transmitter contains the complete signal processing electronics and the failsafe routing of the measurement signal for the measuring computer, with extensive self-monitoring. The embedded software linearises the measuring signal and compensates for the effects of temperature. As a result, correct readings are transmitted even with weather related fluctuations in temperature. In addition, the transmitter can be connected to a gas measurement computer for the option of transmitting service, maintenance, and error messages.

Universal signal transmission

The ZD 22 Transmitter transmits the signals either using an analog (0.2 1mA / 4-20 mA) current interface or a digital (RS485) Modbus interface. This permits the universal use of the trasmitters in combination with GfG gas measurement computers and thus connection to a safety system, so that you and your systems will benefit from the best possible protection.

There are a variety of applications for the ZD 22 in regard to sensors, status LEDs and optional analog or digital interface, "Zero" key to calibrate the zero point, test socket and a potentiometer for the calibration of the sensor.

Weather protection

A weatherproof housing not only protects transmitters against exposure to wind and weather, but also against contamination and excessive temperatures caused by direct sunlight.

Optional colored graphic display

The clear graphic display of the ZD 22 is self explanatory and allows you to read the current status and other important information with ease. The display enables you to navigate effortlessly through the unit s concise menu and to change settings or even calibrate, depending on your user authorization. In the event of an alarm the display changes color from green to red. Two LEDs indicate the status.

Operation buttons

The buttons on the transmitter allow the unit to be calibrated and settings to be adjusted through the menu as needed.

Calibration adapter

In order to perform a calibration, a calibration adapter is used on the transmitter, which ensures a uniform and secure supply of gas.

Easy and convenient service

GfG offers full after-the-sale commissioning and field service support.

• Long service life of the sensors
• Extremely fast response time: t90 < 5 sec.
• Reduced pressure, humidity, or temperature influence
• No damage due to CO₂
• Cost effective single-man adjustment
• Affordable operation costs
