Extech dataloggers – Extech Instruments
Extech Instruments launched the Extech TH30, RHT30, and RHT35 compact dataloggers. The new family of three environmental recording instruments is designed to provide HVACR professionals with easy access to real-time temperature, humidity, and barometric pressure readings as well as insights compiled from extended readings preformatted in Excel® or PDF® report formats.
About the size of a large key fob, each of the three new dataloggers is designed for everyday use in troubleshooting HVACR and IAQ issues related to temperature, humidity, and barometric pressure. HVACR technicians, commercial facilities managers, IAQ professionals, and workplace health managers alike can use the dataloggers to monitor a location for an extended period of time in response to occupant complaints or as part of standard predictive maintenance.
Users can set the dataloggers with a customizable recording rate from once every 30 seconds to once every two hours and a capacity of up to 48,000 combined, total readings with date and time stamps. For multi-site logging, readings can be associated with up to eight locations. Technicians and occupants can quickly check current readings on the large, high visibility LCD. When reporting is required, the dataloggers can be connected to a PC or laptop to output readings in a Microsoft Excel or Adobe PDF format.
The Extech TH30 simultaneously measures temperatures ranging from -22 to 158°F (-30 to 70°C) using an internal NTC thermistor sensor and an external probe. Using the probe’s long 84-in cord, the external sensor can be placed in nearby registers, returns, vents, rooms, or other locations to easily contrast temperatures. In addition to the internal temperature sensor, the RHT30 adds full range relative humidity measurement capabilities (0.1 to 99.9% rh). The RHT35 measures temperature, humidity, and also leverages a MEMS sensor for barometric pressure from 300 to 1100 hPa (8.9 to 32.5 inHg).
