Libratherm offers Microprocessor based Humidity and Temperature Controller Model HTC-3003 and HTC-3000 with input and output suitable for measuring and controlling the T and RH of stability or environmental test chambers. These chambers are mainly used in Pharma, Petroleum, Chemical and Food Industries to test the sample under the desired simulated levels of temperature and humidity. The controller accepts input from the standard T + RH sensors consisting of (Pt-100) temperature sensor and the capacitive type RH sensor or from T + RH transmitter.
In model HTC-3003, the process values and set values are displayed simultaneously in the range of 0.0 to 99.9oC and 0.0 – 99.90% RH respectively on 4 independent 3 digit 7-segment Red / Green LED displays. The real time is displayed on 4 digit display. In model HTC-3000, the process values and set values are displayed on the same 4 digit display with 2 digit display for the respective unit. The display will scan at the programmed rate and indicates T and RH alternately. HTC-3000 has only advantage of HTC-3003 is that of temperature can be indicated up to 200.0 oC. The real time is displayed on 6 digit display. Otherwise both the models are similar.
Specially designed window based E-Chamber Software (as per our standard or as per CFR compliance) does the on line data logging and plot the online/offline graph on the PC and also allows user to enter the set points and control parameters through PC and the controller.
