• 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: clearly structured measurement menu for volume flow and parallel determination of air velocity, volume flow and air temperature

• Precise: automatic absolute pressure compensation guarantees accurate measurement results

• Convenient: integrated telescope that can be extended to 0.85 m, with scaling, makes it easy to measure in any cross-section

• Intelligent calibration concept

For measurements in ventilation ducts: use the hot wire probe (with the compatible measuring instrument) to measure air velocity, volume flow and air temperature.
