Immediate valve positioner replacement on site
-
Valve replacement kit for two valve positioners
-
Compatible with testo 549, testo 550, testo 557 and testo 570
Use the valve replacement kit to replace valve positioners on digital manifolds from Testo. Particularly useful: you can replace the valve positioners yourself – directly on site.
-
Easy to use
-
Reliable measurement data management
-
Including USB data cable
Easy and efficient measurement data management with the EasyKool PC software: the software allows you to transfer measurement data from the appropriate measuring instrument to the PC, then analyze them and print them out. The EasyKool software offers numerous practical functions, such as the creation of measurement protocols or refrigerant updating.
-
Short response time of 2 seconds
-
Very large measuring range: -60 to +1000 °C
-
Waterproof
-
Thermocouple type K
Fast, flexible and waterproof: the immersion probe is ideal for carrying out accurate immersion measurements in various liquids.
-
Intuitive: clearly structured measurement menu for volume flow and parallel determination of air velocity, volume flow and air temperature
-
Precise: detects the smallest air velocities from as little as 0.1 m/s – ideal for laminar flow measurements in cleanrooms
-
Convenient: Bluetooth connection between measuring instrument and probe, with a practical button on the handle for storing individual readings, convenient measurement at ceiling outlets with optional telescope (up to 1 m)
-
Intelligent calibration concept
Ideal for air outlets in cleanrooms: use the high-precision vane probe (with the compatible measuring instrument) to measure even the lowest air velocities and volume flows as well as the temperature. The readings are transmitted directly to your measuring instrument via Bluetooth, making your measurements particularly convenient.

and parallel determination of air velocity, volume flow, air temperature and humidity
-
Precise: accurate measurement results from 0 to +50 m/s and automatic absolute pressure compensation
-
Convenient: probe with a practical button on the handle for storing individual readings, convenient measurement in any cross-section with scaled telescope (up to 1 m), optionally extendable to 2.0 m
-
Intelligent calibration concept
For measurements in ventilation ducts: use the hot wire probe (with the compatible measuring instrument) to measure air velocity, volume flow, air temperature and humidity.

-
Intuitive: parallel determination of relative humidity and air temperature in indoor areas, including long-term measurement
-
Precise: includes absolute pressure compensation, calculation of wet bulb temperature, dew point and absolute humidity
-
Convenient: simply plug the probe head onto the extendable telescope for air velocity probes – and use the adapter to attach them to the universal handle with Bluetooth® or cable (available to order separately)
-
Intelligent calibration concept: only send in the probe head for calibration
More applications, less equipment: if you already own one of our probes with a universal handle, you can easily expand your portfolio of probes with the hot wire probe head.
-
Intuitive: clearly structured measurement menu for long-term measurement and determination of illuminance according to the V-lambda curve (suitable for all common light sources)
-
Precise: standard-compliant accuracy according to DIN EN 13032-1 and class C according to DIN 5032-7
-
Convenient: non-slip probe contact surface for convenient positioning at the measuring location
-
Intelligent calibration concept
For measurements in workplaces, for example in offices or in production areas: use the lux probe (with the compatible measuring instrument) to measure illuminance.
