High and Low temperature test chamber
Stop guessing whether your products can survive extreme climates. From severe winter freezes (-70℃) to engine-level heat (+180℃), our thermal testing chambers expose physical embrittlement, solder joint fatigue, and thermal expansion mismatches before your products hit the market
Why Skipping Thermal Testing is a Costly Gamble？
Temperature fluctuations can cause materials to expand and contract at different rates. Without rigorous testing in a high-low temperature chamber, you risk catastrophic field failures, voided warranties, and rejected certifications.
Prevent Cold Embrittlement & Shattering
What it does:
Plastics, rubbers, and cables that function perfectly at 25℃,will become dangerously brittle at -40℃. Just A single winter freeze can cause outdoor equipment seals to shatter, leading to massive water ingress and total system failure.
The Benefit:
Our JCT-HU/HUU high and low temperature test chambers plunge to -40℃ or -70℃ using industrial compressors. We help you find the exact freezing point where your materials lose elasticity, ensuring your products survive the harshest arctic conditions.
Expose Thermal Expansion Mismatches
What it does:
When after electronic assemblies ,as like a metal chip soldered to a PCB,heating up and cooling down, the materials expand at different rates. Over time, this microscopic pushing and pulling shears the solder joints, causing sudden short circuits.
The Benefit:
By executing rapid hot-to-cold thermal cycling (-40℃ to +180℃) in our high and low temperature test chambers, we force these hidden mechanical stresses to the surface in just a few days, this will allow you to perfect your structural designs before mass production.
Guarantee Audit & Certification Compliance
What it does:
You try to enter the automotive or military supply chain, but your testing data is rejected because it was generated by cheap, uncalibrated equipment with massive temperature fluctuations.
The Benefit:
We utilize precision PID control to guarantee a strict ±0.5℃ temperature fluctuation. Our JCT high and low temperature test chambers output highly repeatable, traceable data .They can instantly satisfy strict GB, IEC, and MIL standards.

Applications
Automotive Electronics
Vehicular electronics are subjected to brutal thermal extremes, from freezing -40℃ winter mornings to scorching +150℃ engine compartment radiant heat. Our high-low temperature chambers perform rigorous thermal cycling on dashboard screens, ECU modules, and under-hood sensors. This validates that critical automotive plastics won’t melt and screens won’t black out or crack under real-world traffic conditions.
telecommunications
Outdoor 5G telecom racks and base station routers face relentless environmental stress, including freezing nights and blistering summer days. Constant temperature fluctuations cause metal and plastic enclosures to warp, leading to moisture ingress. By subjecting telecom antennas to rapid hot-to-cold or cold-to hot in our JCT high and low temperature test chambers, you can ensure structural integrity, seal durability, and uninterrupted signal transmission regardless of the climate.
led lighting
Outdoor LED lighting fixtures and their drivers must initiate instantly in below-zero environments ,while effectively dissipating heat during operation. Hot to Cold Thermal cycling exposes micro-cracks in LED potting compounds and solder joints caused by thermal expansion. Testing in our high and low temperature chambers verifies that streetlights and industrial lighting systems will not fail prematurely due to winter cold starts or summer overheating.
plastic polymers
For Industrial polymers and plastic housings, which function perfectly at room ,but temperature can become dangerously brittle and shatter under stress when exposed to -40℃.
Our high-low temperature chambers determine the precise transition temperature and brittleness timeline of your materials. This data is critical for preventing outdoor equipment enclosures and plastic seals from cracking during extreme winter conditions.
Aerospace & Military Components
Aerospace navigation sensors and satellite valves must operate flawlessly ,while transitioning from high-altitude deep freezes to atmospheric reentry heat.
Our JCT-HUU series utilizes binary cascade refrigeration to push aerospace materials down to an extreme -70℃. This intense thermal stress screening guarantees that mission-critical military and aviation hardware maintains perfect calibration without mechanical binding or sensor drift.
semiconductors and PCB
When PCBs undergo heating and cooling, different materials like copper traces, epoxy substrates, and solder joints expand at different rates. This high and low temperature thermal expansion mismatch will create immense mechanical stress. By running rapid thermal cycling (-40℃ to +150℃), our chambers accelerate solder joint fatigue. This exposes weak soldering and micro-cracks, completely eliminating the risk of sudden short circuits in complex consumer electronics

FAQ
Q1: What is the difference between a high-temp chamber and a high-low temperature chamber?
A high-temp chamber only heats to a high temperature. Such as JCT-HT series.
A high-low temperature chamber (JCT-HU series) integrates a robust mechanical refrigeration system, allowing it to cycle between extreme heat (+180℃) and deep freezing (-70℃) to test material expansion and contraction.
Q2: Why do I need to test down to -40℃ or -70℃ if my product is used indoors?
Even if used indoors, your products are shipped globally. Cargo holds in airplanes and shipping containers in winter easily reach -30℃ to -40℃.
If untested, your product’s internal solder joints or plastic housings may crack during transport before the customer even opens the box.
Q3: Do I need the JCT-HU (-40℃) or the JCT-HUU (-70℃) series?
For standard automotive, telecom, and consumer electronics, -40℃ (JCT-HU) is the industry standard. If you are testing aerospace components, military hardware, or extreme-climate outdoor equipment, you must use the -70℃ (JCT-HUU) series.
Q4: How do I get the testing data for my ISO/GB compliance audits?
The smart PLC controller allows you to export real-time temperature logs and thermal curves directly via a USB drive. You get an instant, unalterable excel/CSV file ready for the third-party quality audits.
Q5: What is the lead time if I order a custom JCT-HU chamber today?
Standard models take approximately 15-20 days to assemble, calibrate, and pack. Highly customized units typically require 4 weeks. Please Fill out the form below for a precise timeline.
