Explosion-proof test chamber for testing batteries and other flammable materials

High-temperature testing sometimes involves materials that can generate sudden pressure increases. To address these risks, this model of temperature test chamber includes a pressure relief vent integrated into the top of the chamber. If abnormal conditions occur, the vent opens automatically to release excess pressure and protect operators. This type of testing equipment is ideal for testing batteries and other items where venting capability is important; it also helps reduce the chance of accidents and equipment damage during testing processes.

Standard Configuration

2 sets of specimen racks
1 Cable port (Ø50 mm): with a white hard rubber plug and cover for PH models. Supplied with only a cover for PHH models
1 vent port
1 terminal block for controlling specimen power supply

Features

A built-in pressure relief vent positioned on top of the chamber to safely vent excess pressure
Automatic activation when internal pressure exceeds preset thresholds
Rapid depressurization to protect operators, prevent damage, and maintain a safer testing environment
