テストー Product Lineup

The "testo 6743/6744" is a pressure dew point transmitter suitable for humidity management of compressed air and dry gases. Equipped with a 4-20mA analog output, it enables effective management of compressed air and control of appropriate dryers, thereby reducing running costs. Additionally, it allows for the selection of atmospheric pressure dew point data when opened to atmospheric pressure, not just pressure dew point. Each parameter setting can be done using the buttons on the main unit. 【Features】 ■ Dew point temperature -45 to +30℃td ■ Maximum and minimum value memory ■ Pressure dew point, atmospheric pressure dew point, relative humidity, absolute humidity, temperature ■ 2 relay signal options ■ Accessories tailored to the connection type *For more details, please download the PDF or feel free to contact us.

The "testo 645X" is a flow meter for compressed air used for managing the flow of compressor air. By managing the flow, it generates energy-saving effects through leak detection and peak load management with distributed treatment. In many factories, the power consumption of compressors accounts for a high percentage, so managing it with a gas flow meter can lead to significant energy savings. 【Features】 ■ Displays flow rate (m3/h, l/min) for standard air ■ Accumulated flow measurement function ■ Easy-to-read color display *For more details, please download the PDF or feel free to contact us.

The "testo 6621" is a compact and stylishly designed temperature and humidity transmitter. It is available in wall-mounted types, including built-in sensor types, protruding types, and duct types, allowing you to choose between models with or without a display and with or without a logo, depending on the installation location. Additionally, we also offer the "testo 6651," which features a digital probe with a humidity accuracy of ±1.7% RH. 【Features】 ■ Durable humidity sensor with ±2% RH accuracy ■ Adjustable and span adjustment available with optional software ■ Compact and stylish design *For more details, please download the PDF or feel free to contact us.

The "testo 6681" is a temperature and humidity transmitter designed for applications that require strict environmental conditions. It offers a measurement accuracy of 1% RH and can meet the stringent demands of high humidity environments where condensation may occur, H2O2 sterilization environments, and pressure dew points. It supports not only analog output but also Ethernet and Profibus. Additionally, we also offer the differential pressure transmitter "testo 6321," which is suitable for compact air conditioning management. 【Features】 ■ High-precision digital probe with humidity ±1% RH and temperature ±0.15℃ ■ Up to 3-channel analog output ■ Outputs: temperature, humidity, absolute humidity, dew point, mixing ratio, mole fraction, wet bulb temperature, enthalpy, water vapor partial pressure, H2O2 mixed dew point ■ Measurement of sterilization environments possible with H2O2 filter ■ Pressure dew point probe down to -60℃ *For more details, please download the PDF or feel free to contact us.

The "testo 6351" is a differential pressure transmitter suitable for controlling and monitoring differential pressures ranging from 50 Pa to 2,000 hPa. In addition to measuring differential pressure, it is equipped with flow velocity and flow rate calculation functions, allowing for management based on flow velocity and other parameters. The automatic zero adjustment feature can be set in five stages, with a cycle ranging from 15 seconds to 10 minutes, enabling stable measurements that are not affected by temperature changes. Additionally, we also offer the industrial differential pressure transmitter "testo 6381," which can manage and monitor not only differential pressures from 10 Pa to 1,000 hPa but also temperature and humidity with a single device. 【Features】 ■ A wide range from 50 Pa to 2,000 hPa ■ Measurement accuracy of ±0.8% of full scale ■ Automatic zero adjustment function using an electromagnetic valve ■ Flow velocity and flow rate calculations ■ Voltage and current output ■ Ethernet and relay output options *For more details, please download the PDF or feel free to contact us.
