SINRAD tech Temperature and humidity test chamber with a 7-inch display LCD touch panel, with a dialogue-style input of data on the screen. Temperature and humidity can be programmed simultaneously, and curves are displayed, including the set value/display value curves. It can display various alarms separately. When a fault occurs, the fault can be displayed on the screen, and the fault can be eliminated, as well as the misoperation. It has multiple groups of PID control functions and precise monitoring functions, and the data is displayed on the screen.

Controller specifications:
a. Precision: Temperature ±0.1℃, Humidity ±1%RH
b. Resolution: Temperature ±0.1, Humidity 1%R.H.
c. Temperature slope: Can be set from 0.1 to 9.9
d. Has upper and lower limit standby and alarm functions
e. Temperature and humidity input signal selection: PT 100Ω×2 (dry bulb and wet bulb)
f. Temperature and humidity conversion output: 4～20MA
g. 6 groups of P.I.D control parameter settings, P.I.D automatic calculation, automatic calibration of dry and wet bulbs
Screen display functions:
a. Touch input, with options directly displayed on the screen
b. The temperature and humidity set value (SV) and the actual value (PV) are directly displayed (in English)
c. Can display the current running program number, segment number, remaining time and number of cycles
d. Function of cumulative running time
e. The temperature and humidity program set values are displayed as graphic curves, with the function of real-time display of the program curve execution
f. Has a separate program editing screen, allowing direct input of temperature, humidity and time
