Extech Instruments, a supplier of test and measurement equipment for the industrial marketplace, announces its new humidity and temperature chart recorder, the model RH520
Easy to set up and operate, the model RH520 offers the best value in paperless chart recorders available in the market today says the company.
The unit can be either desk or wall mounted, and provides simultaneous numerical and graphical displays of humidity (20 to 95% RH) and temperature (-20 to 140F).
The RH520 also calculates dew point.
The multiple graphic displays are cursor controlled and have adjustable X/Y axis resolution which allows the user to monitor both temperature and humidity within a user specified range.
The sample rate is adjustable from 0.1 second to 200 minutes per sample, permitting daily, weekly or monthly graphs.
Extech's RH520 features an internal memory that records up to 49,000 readings with time and date, and can be transferred to a PC for data record-keeping, analysis and printing.
It has a detachable probe that extends up to 1 meter for measurements in enclosed environments.
High and low set points trigger audible and visual alarms, and an external remote alarm module is available.
The basic accuracy of the RH520 is 3.5%RH and 1.8F/1C.
It comes complete with a built-in stand, a humidity/temperature sensor, and three AA batteries.
