707 Carbon Monoxide Analyzer by Test Products International

Use the 707 to measure CO levels in the flue and test ambient CO levels in home and office spaces. Hand held and easy to use.

Test flue gasses at home or office spaces for the presence and location of CO leaks. With a protective rubber boot, the new 707 fits comfortably in your hand and operates with the push of a button.

The TPI 707 Carbon Monoxide Analyzer is a state of the art, easy to use analyzer designed to display carbon monoxide levels in and around appliances and work / living spaces. The instrument is ruggedly constructed and comes with a 3 Year unit and 2 Year sensor Guarantee.

The TPI 707 combustion analyzer uses a state of the art electrochemical sensor. This sensor technology provides the longest lasting, most accurate and reliable means for performing tests. The sensor in your analyzer will need to be replaced periodically and calibration is recommended once every year. The 707 will remind you when calibration is due by flashing "CAL DUE Err" for three seconds at start up if the date of calibration is one year or older.

Electrochemical sensors by nature are always active. Therefore the time the analyzer is off and not being used must be taken into account when determining sensor life. The sensor in your analyzer is warranted for two years. This warranty does not cover a sensor damaged through misuse of the analyzer.

770 Carbon Monoxide Monitor by Test Products International

The 770 CO Single Gas Monitor is a state-of- the-art Carbon Monoxide Instrument designed to measure Carbon Monoxide in ambient air and to perform a carbon monoxide build up test . It has a measurement range of 0 to 999 ppm (parts per million) and displays the readings in 1ppm increments.

The unit features a personal audible and visual alarm, which is factory set at 30ppm CO but can be changed in the field to keep current with government legislation.

Other features include: maximum reading hold, elapsed time and manual zero. The audible alarm may be switched on and off as required. Battery changing is made easy by use of a simple slide off battery compartment cover.

The detector uses an advanced electrochemical sensor that measures Carbon Monoxide and should not be used for any other purpose.

When the audible alarm is switched off a small 'double speaker' symbol will be displayed at the bottom left of the LCD. When the alarm setting is exceeded a 'warning' symbol is displayed at the bottom center of the screen and the red warning indicator is illuminated. As the battery level approaches 2 volts a 'BAT' warning symbol is displayed to indicate low battery level. When the battery level gets too low the unit will automatically switch off.

Features

• Measure CO from O to 999ppm
• Displays the max. CO reading in PPM since power on
• Displays in hours and minutes, time elapsed since power on
• Displays user set value of audible and visual alarm
• The audible alarm can be switched on and off by pressing the SEL button

P250 Non-Switchable Passive Oscilloscope Probe, 250MHz, 1.2M Cable Length by Test Products International

Selecting the correct oscilloscope probe ensures accuracy and can improve the performance of your test instrument. TPI offers a wide range of high quality oscilloscope probes designed to meet the most demanding applications.

The IP series monolithic probes have switchable attenuation and are available in 60 and 250MHz. These probes are ideal for technicians that need a basic oscilloscope probe.

The slimline design P and SP series probes are available in fixed or switchable attenuation. These series of probes are perfect for the technician needing additional features such as replaceable cable and interchangeable probe tip. The compensation adjustment for these probes is located in the BNC to eliminate noise pickup.

TPI also offers three models of high voltage differential probes all with high common mode rejection, wide bandwidth, and fast rise times. Differential probes enable the viewing of signals not referenced to earth ground and provide better performance than a matched pair of single ended oscilloscope probes when measuring these types of signals.

Several important factors must be taken into account when selecting the proper probe.

• The probe should have sufficient bandwidth and rise time for the test instrument and application. Choose a probe with at least an equal bandwidth as the scope it will be used with. For best performance a probe with twice the bandwidth as the scope should be selected
• For oscilloscope probes, the input capacitance of your oscilloscope should be within the compensation range specification of the probe. In addition, if your oscilloscope has readout function, select a probe with this capability
• For differential probes, make sure the maximum differential voltage is adequate for your application and the common mode rejection specification meets the requirements of the tests being performed.

Features

• Attenuation: Ratio of the output signal to the input signal. Attenuation should remain constant decreasing by 3dB only as the frequency increases to the maximum bandwidth.
• Bandwidth: The maximum -3dB frequency that can be expected.
• Cable Length: Length of the cable from the end of the probe to the end of the connector. It is important to use a probe with just enough cable length for your needs. Long cables increase the capacitance and propagation delay of the probe.
• Compensation Range: The range a probe can be compensated to match the input capacitance of the test equipment it is being used with.
• IEC 1010: Probes with the IEC 1010 category rating have been designed for safety.
• Input Impedance: The total resistance and capacitance as measured at the tip of the probe. This specification is used to define the loading effect of a probe. At frequencies under 1MHz the input resistance of the probe will have the most influence. At higher frequencies the input capacitance will have the most influence.
• Max Input Voltage: The maximum voltage the probe can be used at.
• Max Differential Voltage: The maximum differential voltage that can be measured by a differential probe
• Readout: Probes with this capability are compatible with readout function oscilloscopes that automatically detect and display the attenuation factor of the probe.
• Rise Time: The time required for the leading edge of a pulse to rise from 10% to 90% of its final value.
• CMRR: Common Mode Rejection Ratio. A measure of a differential probes ability to reject any signals common to both test points in a differential measurement

Applications

• Use TPI Probes with Bench Top, Portable, Analog, and Oscilloscopes
• Logic signal and waveform tests
• Measure voice / data signals
• Analyze power quality
• Test motor control circuits

The TPI 750a is a state-of-the-art refrigerant leak detector capable of detecting all halogen based gases. The internal diaphragm pump and unique sensor design provide fast and reliable gas sensing. Selectable sensitivity combined with an adjustable tick rate will allow any service professional to pinpoint those tough to find leaks even in contaminated environments.

Sensor life can be extended by fitting a 1/2" long piece of vinyl tubing onto the sensor tip. This tubing helps prevent foreign material from getting into the sensor during tests; clean or replace the tube regularly.

Even though TPI refrigerant leak detector sensors are very durable and can last up to 400 hours, sensor life can be aided by press fitting a 1/2" long piece of vinyl tubing onto the sensor tip. This tubing helps prevent foreign material from getting into the sensor during tests. Clean or replace the tube regularly.
