Description

Full Range Programmable Temperature and Humidity Test Chamber

The FRP Series of humidity chambers is truly the work horse of the Blue M line of humidity chambers, offering an unequaled performance in MIL-STD testing. Its sophisticated yet easy to use control system allows versatility to go beyond military testing, tapping on a vast array of temperature and humidity capabilities while offering traditionally superior Blue M quality.

Blue M humidity chambers can be used for military standard test 883, method 1004 and 202, method 106 moisture resistance tests. Also the 810, method 507.2 electronic subassembly and component qualification, packaging studies and moisture studies can be implemented on the FRP Series of humidity chambers.

Performance

Range 1 - Operation with reservoir filled & low capacity dehumidification.

• Controller Tolerance:
• Temperature: ±1/2°C
• RH: ±1%
• Operation intended to allow control of temp. and humidity conditions typically higher dry bulb temperature and relative humidity. Little or no wattage dissipation from the product under test is tolerated by this condition.

Range 2 - Operation with reservoir filled and time proportioned dehumidification.

Controller Tolerance:

• Temperature: ±1/2°C
• RH: ±2%
• Provides expanded capabilities in terms of the range of controlled conditions and the amount of wattage dissipation tolerated at each condition.

Range 3 - Operation with reservoir drained and time proportioned dehumidification.

Controller Tolerance:

• Temperature: ±1°C
• RH ±3%
• By using Range 3, FRS, and FRP units provide wider range of humidity control, reaching into lower relative humidity ranges of chamber capability. Range 3 provides intermittent use at very low RH conditions, typically up to 8 hours in test duration.
