Precise Mini Temperature Chamber

The OEMTC-100 temperature chamber is small enough for fit on your desk with room to contain  tens of fiber optics components, photonics components or fiber gratings. Wide temperature range and precise temperature stability are suitable for plenty of temperature characteristics tests, such as for sensor, packaged product, temperature tunable filter and any other small products.

Thermoelectric cooler (TEC) avoids any audible noise from big temperature chambers, ovens, refrigerators or coolers. Requiring only small power consumption and you can plug it into any 110V and 220V outlet. Light weight and compact size make it portable. Fibers draw out from side-face openings for real time measurement.

Using optional PC control software, user can observe temperature value, adjust temperature setpoint, compile and execute temperature-time curve. The temperature test procedure is easy and fast.
