Description
testo 735-2 - Multichannel Thermometer with Memory
Calibration of static temperature sensors, temperature measurements in the cosmetics industry, chemical laboratories, the field of cooling and refrigeration technology, the food industry: the testo 735-2 multichannel thermometer can master virtually any application thanks to a wide range of optionally available sensors, a super-size memory, and wireless data transfer.
Your Advantages
- Up to 3 connectable sensors and a further 3 temperature sensors which can be connected wirelessly to the meter.
- Super-size memory for up to 10,000 readings; PC software and USB cable included.
- Extremely accurate sensor (optional) for a system accuracy of up to 0.05 °C.
- Waterproof (IP65) and HACCP / EN 13485 compliant.
Wide Selection of Sensors & 6-Channel Precision
The testo 735-2 digital multichannel thermometer is used in a wide variety of different fields. It can measure the surface, air, and core temperature of a whole range of media with an accuracy up to 0.05 °C using high-precision Pt immersion/penetration sensors. Because it can be wirelessly connected to up to another three external temperature sensors, whose readings are transmitted to the display, you effectively get a 6-channel meter.
The meter features a connecting point for a highly-accurate Pt100 sensor and two connecting points for quick type K, T, J, and S thermoelement sensors. There is a wide selection of immersion, penetration, and surface sensors available to help you carry out quick and accurate temperature measurements on a variety of different surfaces and media. The high-precision, optionally available Pt100 sensor makes this unit ideal for use as a working standard.
Measure, Save and Analyze – For Different User Profiles
The testo 735-2 not only carries out quick and precise measurements, but it also allows you to save up to 10,000 readings, create as many as 99 measuring sites, and provide multiple user profiles. You can save individual protocols or measurement series for each measuring site and select from a memory cycle of between 0.5 seconds and 24 hours.
The included PC software allows you to save and analyze the measuring data as a table or graphic. The instrument provides Delta T, minimum, maximum, and mean values on a backlit display. It features an acoustic alarm that is triggered when thresholds are exceeded and can be paired with the optionally available testo fast printer for on-the-spot data printouts.
Tradie Pro Tip: If you are auditing massive commercial cooling setups or validating clean rooms, the memory function on the 735-2 is unparalleled. Set your logging intervals, let the unit run across up to 6 channels simultaneously, and simply dump the 10,000 data points to your PC later for instant graphical reporting. It eliminates manual clipboard tracking entirely.
