0572 2156 External Temperature and Humidity Probe for Testo 160 E and 160 THE Wi-Fi Data Loggers by Testo

Normally, it is difficult to hide the data logger inside the display cabinet. The testo digital temperature / humidity probe (1.5" x 0.63" / 36 x 16 mm) can be hidden within the case base showing only a small paintable vent cap and the bushing's collar. The data from the probe transfer to the Wi-Fi logger over a thin 1.7 ft. / 0.6 m or an 8.2 ft. / 2.5 m extension cable. The maximum length of combined extension cables is 32.8 ft. / 10 meters.

Applications for the temperature and humidity probe

The temperature and humidity probe is ideal for use in museums, galleries and other exhibit application. Use the high-precision temperature and humidity probe (with external data logger) to measure the temperature and relative humidity in display cabinets. The supplied base plate bushing with an O-ring prevents leakage of external air. Monitor the micro-climate in your display cabinet to see if the artwork maintained at optimal environmental conditions, or if the silica gel pellets need replacing.

Smart probe calibration

The temperature and humidity probe offers maximum digital measurement reliability. As the processing of measuring values is done within the probe, the quality of the measurement is not affected by the length of the cable between the Wi-Fi data logger and the probe. The probe can be sent in for calibration on its own (without the data logger) because the calibration points are stored internally.

• Tiny temperature and humidity probe for use in display cases
• Doesn't effect the air exchange rate in the display case thanks to the wall bushing with an O-ring seal
• "Smart probe" holds internal calibration points
• Measurement range: 0 to 100% relative humidity; temperature 14 to 122 °F (-10 to +50 °C)

Includes:

1 x temperature and humidity probe with plug-in cable (length 1.7 ft. / 0.6 m), base plate mount bushing, and factory calibration document.

GrowControl™ SXR Rain Sensor by Agrowtek

GrowControl™ Rain Sensor is a high quality optical type rain sensor with no moving parts. The rain gauge senses water hitting its outside surface using beams of infrared light. It uses the same sensing principle used in millions of automotive rain sensing windshield wiper controls.

Connect to GC-Pro or GC-Extreme controllers' digital inputs to close vents and windows down to a weather set-point at the first sign of rain.

Equipped with arm for mounting to structure or weather station. Includes a built-in heater to allow use in temperatures down to 32°F (0°C). Smart logic prevents false triggers from dust and other slow build-up of accumulation. Adjustable sensitivity allows for four different settings which activate the sensor from the slightest amount of rain to heavy rainfall.

Operates on 24Vdc from controller and connects directly to any digital input.

AI3161 LabSen 241-180 Glass-body pH Electrode for NMR Tubes (3mm diameter, 180mm length) by Apera

Built with proprietary sensor technology and premium materials from Switzerland, Apera LabSen 241-180 Glass Micro pH Electrode is designed for micro-volume samples in slim containers such as NMR tubes (minimum sample volume: 50 microliters).

LabSen Glass Membrane - LabSen 241-180 pH electrode adopts an ultra-long 180mm micro cylindrical glass membrane (ø3mm), making NMR tube pH measurement easier than ever. And it can be tested at high-temperature up to 212°F. The low-resistance membrane (<450MΩ) helps you quickly get a fully stabilized reading.

Long-Life Reference System - composed of a glass tube, AgCl, and a reference silver wire. The top end of the slim glass tube is stuffed with cotton, which prevents the reaction between AgCl and electrolyte when the temperature changes. It improves the stability of the reference system and extends the electrode's service life.

The electrode uses a standard BNC connector, compatible with any pH meters that use BNC connectors. No temperature sensor is built-in. Users need to have a separate temperature probe (ex: Apera Instruments MP500) to enable ATC or manually input temperature to achieve temperature compensation.

94155-A Focus Motor for SCT and EdgeHD by Celestron

The Focus Motor for SCT & EdgeHD provides electronic focusing for Celestron Schmidt-Cassegrain (SCT) and EdgeHD telescope optical tubes. With the focus motor installed, you can bring celestial objects into sharp, precise focus using your telescope's hand controller or a computer instead of using the focuser knob. A focus motor is great for visual observers who want to dial in exact focus (especially those with dexterity issues) and a must-have accessory for astroimagers. With a motorized focuser installed, an astroimager no longer needs to be physically near the telescope to focus an image. Combined with computerized control of the mount and camera, the focus motor enables the imager to gather data remotely from a backyard observatory, or even a telescope located hundreds of miles away. As an added bonus, port covers protect the ports while not in use, and the covers cannot be lost due to the tethered design.

• The Celestron Focus Motor for SCT and EdgeHD enables electronic focusing using a computer or Celestron computerized mount hand controller for remote/hands-free observing.
• Self-powering: When connected to a Celestron computerized mount, the mount provides the power. When connected directly to a computer, USB provides the power.
• Compatible with a wide variety of Celestron Schmidt-Cassegrain, EdgeHD, and Rowe-Ackermann Schmidt Astrograph optical tubes. Check description for full list.
• Motor controls include multiple speed rates, automatic GoTo indexed focuser position, and focuser backlash compensation.
• Focuser Utility software for Windows provides a simple user interface. Also compatible with Celestron PWI.
• Enables autofocusing with a camera and third-party software via ASCOM.
• Indexed focus position allows the motor to automatically return to a previous focus position and prevents the focus motor from reaching the end of telescope's mechanical focus travel.
• Now compatible with the 9.25" EdgeHD.

Compatible Optical Tubes

The focus motor is compatible with all SCTs from 6" to 14" in aperture that have been produced since the year 2006. It is not compatible with 5" SCTs or older models. It is compatible with the 8" Rowe-Ackermann Schmidt Astrograph (RASA), the 36cm RASA, the 7" Maksutov-Cassegrain, and all the EdgeHD optical tubes. It can also be used with the 11" RASA, but requires the Focuser Retrofit Kit for RASA 11.

For 6" Schmidt-Cassegrain telescopes only, the Off-Axis Guider (#93648) cannot be used when the focus motor is installed due to mechanical interferences.

Power Options

There are three options for powering your Celestron Focus Motor:

1. When using a Celestron computerized mount, you can power and control the focus motor through the mount using the supplied AUX cable. This allows control from the mount's hand controller (NexStar+ or StarSense) or a computer.
2. If you are not using a Celestron mount, you can power and control the focus motor from a computer USB port.
3. You will need a user supplied USB A-to-B cable. You may also opt to use an external 12V DC power source which plugs into the motor's power jack.

Compatible Software

Celestron offers a free Focuser Utility program for computer control. The Celestron PWI software can also control the focus motor. To use third-party focuser control software, an ASCOM driver is needed.
