Testo's new TestoKool Line of digital manifolds for commercial and industrial refrigeration systems is designed to provide one integrated meter for measuring, recording, and regulating refrigeration systems. The TestoKool 560, the most advanced model in a series of four, features direct measurement of refrigerant pressure/suction up to 735 psi, an external temperature probe that reads from -150° to 750°F, and a built-in vacuum gauge. All meters operate on standard batteries or power supplies. Other units in the series measure only vacuum or only temperature and pressure.
The new Air Velocity Probe Model 8592 from TSI Incorporated lets Q-Trak™ Plus users measure air velocity at diffusers, in ductwork, and at fume hood faces. The accessory probe also allows for quick calculation of volumetric flow rate. Velocity measurements are displayed in real time along with temperature, humidity, CO, and CO2. The probe quickly attaches to the Q-Trak Plus accessory port for easy use, and data can be stored and downloaded using TrakPro™ Data Analysis software.
