HCH20- Humidified incubator/Environmental chamber

The HCH20 one door environmental test chambers/humidified incubator can maintain temperature from 4°C to 50°C with precision and relative humidity of 50% to 90% humidification. This chamber is aptly used as an environmental testing & growth chamber due to its wide temperature and additive humidity range. Typical chamber application includes

  • Ninhydrin testing

  • Drywall (gypsum) stability testing

  • Cement curing testing

  • Product/packaging shelf life testing

  • environmental testing

  • environmental growth

  • Any scientific stability testing 

Chamber features all stainless steel interior and exterior construction with 2″ polyurethane CFC free insulation.

Cabinet standard features

  • Stainless Steel Exterior & Interior

  • Maintains temperatures between 4°c to 50°c

  • LED interior light

  • Recessed Door Handle

  • Door locks standard

  • Magnetic door gasket standard for positive door seal

  • Pre-Installed 4″casters with bumper brakes

  • Three (3) Pre-Installed shelves per section

  • Back wall plenum for even distribution of conditioned air

Chamber uses thermoelectric assembly for heating and cooling. This type of cooling/heating system completely eliminates need for conventional refrigeration system and failures due to mechanical components such as compressors thereby drastically increasing the life expectancy of each chamber. Maintenance cost is also lowered by the thermoelectric/Peltier driven heating/cooling system. The chamber is quiet  while in operation. Chamber temperature set points are tightly controlled using PID controller. Chamber comes with additive humidification via ultrasonic humidifier, humidity sensor and PID humidity controller which displays process and set value.

Standard Temperature control features:

  • Log Controller Data

  • Control access, alarm notification via app ( Watlow model)

  • 2 programmable alarm

  • IP-65 Panel (front panel splash proof)

  • CRC protocol correction build in for error free communication

  • Visually interpret thermal data

  • Set multiple target temperatures and program steps for advanced applications like thermal cycling

  • Save and load script parameters from stored files on your disk drive

  • Multiple jumps and loops function for complex testing profile

  • *Note: We offer 2 controller models- Not all features may be available in one controller- Please refer to controller spec.sheet

Humidity control features:

    •  3% accuracy over the entire input range

    • Displays both the set point and actual relative humidity

    • On/off controller is  standard. if you need PID controller with tighter control up to 1% RH- please contact us.

    • A fast response, capacitive relative humidity sensor is included. It has high accuracy, high reliability, consistency

    • Dual alarm outputs with 10+ activation methods/situation

    • High brightness, large LED display – easily read from distance.
