Features:

Excellent performance and high precision.
  With a temperature and humidity range of +15℃～+60℃/50%RH～90%RH, the chamber can achieve a Temp./humid. max-min range of ±1℃/5%RH to meet the relatively higher requirements of stability testing.
  Note: The ICH Guidline Q1A standards is ±2°C/±5%RH.
Balanced temperature and humidity control system (BTHC system), Virtual air jacket system.
Vacuum Insulation.
  HG model stability test chamber is the first in the environment test chamber industry to adopt vacuum insulation.which reduces the effect of ambient temperature.
Full-view inner glass door.
  Full-view inner glass door is equipped as standard. It lets you easily check on samples without temperatureand humidity fluctuation that caused by opening andclosing the outer door.
Reliable temperature andhumidity sensor.
  A high-accuracy resistance temperature detector (Pt100) is used for the temperature sensor, and a capacitive thin-film polymer sensor is used for the humidity sensor,You are free from wet-bulb wick replacement in dry-bulb systems and the effects of microorganisms that have become attached to the wick.
Smooth specimen access.
  Sliding shelves are used to allow easy access to specimens. Shelves can be pulled out to one-half of their depth. When heavy specimens such as liquids are placed onthe shelves, a fall-prevention mechanismkeeps them from being pulled out when slid forward. (Equally distributed load per shelf is 30kg).
Cable port （θ25mm）for validation.
  A cable port that can be used to insert a temperature and humidity distribution measurement sensor is standard. A slicon rubber plug is also included to ensure air tightness when the sensor is inserted in the chamber.
Color LCD touch paneland Multilingual display.
  Easy-to-use color LCD touch panel is included as standard. It is much easier to set various patterns of Constant-, Program-, Remote-Operation to meet various testing conditions.
Multilingual display.
  Can change the display lauguage from English to Simplified Chinese,Japanese at any time from the lanuage icon on the top of the display.
USB output of trend graph data.
  Data can be recorded directly to a USB flash drive,backup and measurement intervals and other setting can be configured as required.
Easy maintenance.
  Maintenance work such as cleaning thecondenser fins and filling the water tankcan be easily operated.

※1 The performance values are based on IEC 60068-3-6:2001, JTM K09; 2009.Performance figures are given for a +5°C to +35°C ambient temperature
(Ambient temperature +18°C to +35°C for setting temperature over +40.1°C),relative humidity 65±20%rh, rated power supply and no specimens inside the test area.
※2 Temperature and humidity maximum and minimum range means maximum difference after stabilization, at any moment in time in the working space against the setting values.Ambient temperature of +5°C to +32°C,no load,no specimens .
