Temperature Chambers — Test Equity 105 Half Cube Temperature Chamber (My Store)

How Much Does Test Equity 105 Half Cube Temperature Chamber Cost in 2026?

The Test Equity 105 Half Cube Temperature Chamber is typically priced at $5,500 in 2026, with a narrow range due to its limited condition variability. Units in "B" grade condition, which is typical for this model, are available through refurbishment channels like Ferrotec and Axus Technology. These vendors offer savings of 40–60% compared to a new unit, which can cost upwards of $13,000.

If you delay replacing a failed chamber, you could face a minimum of $2,000 in daily downtime costs in a high-volume production environment. It's important to note that while the price is stable, the condition of the unit is not always consistent. Units over 10 years old may require more frequent maintenance, and some may have been modified in the field, which can affect performance and compatibility.

Test Equity 105 Half Cube Temperature Chamber Specifications and Compatible Tools

The Test Equity 105 Half Cube Temperature Chamber typically offers a temperature range of -65°C to +150°C, with a standard resolution of ±0.5°C. It commonly supports a ramp rate of 10°C per minute and has a chamber volume of approximately 0.5 cubic feet. These chambers are often used with test systems from companies like Keysight and National Instruments, particularly with models from the 2005–2010 production cycle.

However, this model is not compatible with newer automated test equipment (ATE) systems that require full-cube chambers or advanced data logging. Specifically, it is incompatible with the Keysight 3070 series due to its lack of a full-size interface port. If you attempt to use it with incompatible systems, you may experience data loss or inaccurate test results, which can cost up to $5,000 in rework and lost yield.

What to Check Before Buying a Used Test Equity 105 Half Cube Temperature Chamber in 2026

1. Verify the production year. Units manufactured before 2010 are more likely to have outdated control boards and may require additional parts.
2. Perform a thermal cycle test. Run a test from -65°C to +150°C and back to ensure the chamber reaches and maintains setpoints within ±1°C.
3. Inspect the internal insulation and seals. Look for signs of wear or degradation. Reject the unit if the door seal is damaged or if there are visible gaps.
4. Check the control system logs. Units should have at least 10,000 thermal cycles logged. Units with over 15,000 cycles may have a higher risk of compressor failure.
5. Request a full calibration report. Without it, you risk inheriting a unit that may fail within the first 6 months of use, costing up to $3,000 in unplanned repairs.

FAQ

Q: Can I use the Test Equity 105 Half Cube with a Keysight 3070 test system?
A: No. The Keysight 3070 requires a full-cube chamber with a full-size interface port. Using the 105 Half Cube with it will result in data loss and failed tests.

Q: Should I buy a unit with over 12,000 thermal cycles?
A: It depends. Units with over 12,000 cycles may still be functional, but the risk of compressor failure increases by 30%. If the unit is under $5,000, it may be worth the risk, but ensure the seller provides a 6-month warranty.

Q: How long can I expect the Test Equity 105 Half Cube to last with regular use?
A: With proper maintenance, including annual calibration and seal inspection, you can expect 8–10 years of service. Units over 10 years old may require more frequent repairs.

Q: How does the Test Equity 105 Half Cube compare to the Ferrotec FC-120 in performance?
A: The Ferrotec FC-120 offers a slightly wider temperature range (-70°C to +160°C) and a faster ramp rate of 15°C per minute. However, the 105 Half Cube is more compact and better suited for benchtop use.

Q: What is the average cost of a calibration for this chamber?
A: Calibration typically costs between $450 and $600, depending on the vendor. If you skip it, you risk inaccurate test results, which can cost up to $2,500 in rework.
