BHD-502
BenchtopRack and Stack
The BHD-502 is a benchtop-style environmental test chamber for temperature and humidity testing. The chamber is designed to fit on your lab table and still have easy and safe access when you reach-in the workspace.
If you are concerned about losing your lab counter space, this test chamber has an optional floor stand for one chamber or get double the test workspace when you stack two BHD Test Chambers in the same footprint.
STRUCTURE. The internal workspace is lined with type 304 stainless steel for a vapor-tight internal construction. The exterior has a durable powder-coat finish over heavy-gauge steel for a long-lasting clean look. Between the two layers is highly-efficient, low k-factor, thermal insulation. This chamber is built to last for many years.
CIRCULATION SYSTEM. Air circulation is crucial for environmental testing. The BHD-502 Test Chamber has a proprietary baffle and fan design combination. This optimizes temperature and humidity conditions within the workspace.
HEATING SYSTEM. HD test chambers feature heating systems equipped with open ceramic-core nichrome heaters for reliable and accurate temperature control within ±0.5°C.
HUMIDITY SYSTEM. The humidity system has a standard range between 10% and 95%. To extend your humidity range, see the optional features section. View RH Chart.
COOLING SYSTEM. The cooling system in the is BHD-502 consists of a self-contained, compact, single-stage, mechanical refrigeration system with an air-cooled condenser. An optional water cooling condenser is available.
Add boost cooling with liquid LN2 or CO2 to shorten pull-down times; it's a great option for stress tests that require rapid cooling.
INSTRUMENTATION. BD-502 Test Chamber incorporates AESONE CONNECT creating a robust connected device giving you a standard and uniform interface that makes operation easier. Learn more in the Instrumentation Tab below.

*Rise and pull-down rates calculated using IEC 60068-3-5 standard. Custom options available.
*Ideal ambient temperature conditions for test chambers is 23°C (73.4°F). The temperature and humidity range of assured performance is between 15°C and 25°C (59°F/77°F) and 30-50% relative humidity. Conditions outside this range may affect the performance of your test chamber and reduce the lifespan of the equipment.
Notice for Customers Requesting R449A:
Consult our sales team regarding the use of R449A refrigerant (where applicable). This substitution ensures compliance with relevant regulations. Please be aware that the use of R449A will change the achievable low temperature to -35°C. Our sales team can provide detailed information regarding this change for your specific application.
