3 GROUP ZONE PID ALGORITHM

Complete temperature range is divided into three

zones (LOW/MIDDLE/HIGH) and each ZONE has

its individual PID Algorithm to provides precise

and superior temperature control characteristic

of whole temperature range.

3 POINT CALIBRATION FUNCTION

An excellent calibration tool to calibrate chamber

at THREE DIFFERENT TEMPEATURE POINTS

to adjust multiple TEMPERTURE BIAS

to increase temperature accuracy

of whole temperature range.

1 POINT OFFSET CALIBRATION

Provides simple and easy calibration tool

to calibrate chamber at ONE SPECIFIC

TEMPERTURE POINT of frequent use.
