HVAC TRANSMITTERS AND HYGROSTATS
Ensuring an environmentally friendly workplace , cleanroom operation or storage space for specialised products that meet the most stringent parameters of humidity and temperature measurement can be achieved with the newly launched HVAC40 Thermo-Hygro transmitter from Delta OHM .
The HVAC40 has a unique design which gives high accuracy , greater connectivity , stability and operational simplicity .
The LED display makes it easy for technicians to note the health state of the HVAC system and immediately address any alarm activations . The instruments are factory calibrated and ready for immediate use . Three models of the Delta OHM HVAC40 can be supplied as a temperature version only or as temperature / humidity / Dewpoint versions . All are available with or without display functions .
The HVCAC40 series can perform in any environment due to its stainless steel filter that protects the sensor against dust and particles . The main areas of application include HVAC , building automation , cleanrooms , agriculture and humidifiers .
APP-CONTROLLED DIGITAL REFRIGERATION MANIFOLD
The testo 550i , with Bluetooth and 2-way valve block , is the smallest fully-digital manifold on the market which can be completely controlled by a smartphone or tablet .
Since the manifold does not have a built-in display the cost saving is transferred directly to the technician . At the same time , it guarantees maximum reliability thanks to its robust housing with IP54 protection class .
It communicates wirelessly and automatically via Bluetooth 5.0 with the wireless testo Smart Probes for temperature , vacuum pressure and humidity , and calculates parameters automatically in the testo Smart App . The testo 550i thus saves considerable time and money in daily servicing and maintenance work .
