Benchtop Temperature Humidity Test Chamber

The ZKS4008 benchtop temperature humidity test chamber delivers -40C to +150C precision control for components, modules, and finished products - engineered by ZKSSUN with custom configurations, high long-term stability, and a dedicated engineer for every account.

Product Overview
What Is the ZKS4008 Benchtop Temperature Humidity Test Chamber?
The ZKS4008 is a benchtop temperature humidity test chamber built for development, test, and reliability engineers who need to validate whole products, mechanical components, and raw materials under controlled high-low temperature and rapid temperature-change conditions. It supports environmental stress screening (ESS), accelerated life testing, and standards-based qualification for electronics, automotive, new energy, and defense-related products.

Balanced Temperature System
Closed-loop PID control with multi-point PT100 and thermocouple sensing for repeatable, audit-ready data.

Rapid Temperature Change
Approx. 3.2C/min heat-up and 2.1C/min pull-down rates support accelerated ESS profiles.

Patented Safety Design
Water and electrical systems are physically separated (Patent No. ZL201220245236.8) to reduce leakage and short-circuit risk.

Standards-Ready
Configured to meet GB/T2423, GJB150, IEC60068-2 and MIL-STD-202G-103B test requirements out of the box.

Everything Engineers Need to Evaluate the ZKS4008
Use the tabs below to jump straight to what matters for your evaluation - pain points we solve, engineering advantages, full specifications, a head-to-head comparison, applications, and answers to common technical questions.


Common Challenges Reliability & Test Engineers Face
Displayed vs. Actual Temperature Gaps
Chamber readouts hit setpoint while the DUT itself lags behind, undermining test report credibility during audits.

Slow Recovery After Door Opening
Long recovery time after loading samples extends test cycles and disrupts lab scheduling.

Self-Heating Samples Skew Results
Power modules, batteries, and other heat-generating DUTs exceed chamber refrigeration capacity without proper load data.

Standard Chambers Fail Aerospace/Aerospace Specs
GJB150 and MIL-STD-202G programs require ramp rate and uniformity performance many commercial chambers can't meet.

Slow After-Sales Response
Alarms or performance drift with no engineer available for remote diagnostics stall the entire test line.

Hard-to-Compare Specifications
Marketing language obscures whether a "budget" chamber sacrifices long-term stability and control accuracy.
