Furnaces — Used Applied Test Systems 3350-CA (Applied Test Systems)

How Much Does Used Applied Test Systems 3350-CA Cost in 2026?

The used Applied Test Systems 3350-CA furnace typically sells in the $9,500 range in 2026, with a few models commanding slightly higher prices depending on condition and included accessories. Units in condition grade B, which is typical for this model, usually fall within this bracket. Refurbished units from vendors like Ferrotec and Axus Technology can often be found in this range, with Axus offering a 12-month warranty on their reconditioned models.

Compared to a new 3350-CA, which can cost upwards of $24,000, the used option offers a 40–60% cost savings. This can translate into significant budget flexibility, especially for smaller labs or R&D teams. However, buying a poorly maintained unit can result in unexpected downtime and repair costs, potentially exceeding $5,000 in the first year.

Condition is a critical factor. Units with more than 10,000 operating hours or signs of thermal cycling damage may require more extensive maintenance. Always request a full service log and thermal performance test before finalizing a purchase.

Used Applied Test Systems 3350-CA Specifications and Compatible Tools

The Applied Test Systems 3350-CA is a benchtop furnace commonly used for thermal testing of semiconductor materials and components. It typically operates in a temperature range of 25°C to 1,100°C, with a standard ramp rate of 10°C per minute. The unit is equipped with a programmable controller and typically includes a PID temperature control system.

These furnaces are often used in conjunction with semiconductor test systems like the Keysight 34972A and older Agilent 34970A models, particularly those from the mid-2000s. However, they are not compatible with newer systems like the Keysight 34980A due to differences in communication protocols and power requirements. Using an incompatible controller can lead to system instability and potential damage to both the furnace and the test equipment.

The typical lifecycle of a 3350-CA is around 8–10 years with regular maintenance. Units with more than 12,000 thermal cycles or over 10 years old may require more frequent calibration and component replacement. A failed heating element or thermocouple can bring testing to a halt, costing labs an average of $3,000–$5,000 in lost productivity and repair costs.

What to Check Before Buying a Used Applied Test Systems 3350-CA in 2026

1. Service History and Age: Request a full service log. Units over 12 years old may have outdated components and require more frequent maintenance. A furnace older than 15 years is a hard reject due to obsolescence and lack of support.

2. Thermal Performance Test: Ask the seller to provide a recent thermal performance test. The furnace should maintain a temperature stability of ±1°C at 1,000°C. A deviation beyond ±2°C indicates potential sensor or controller issues.

3. Heating Element and Thermocouple Condition: Inspect the heating element for signs of wear or discoloration. A thermocouple with more than 10,000 thermal cycles should be replaced. A failed thermocouple can lead to inaccurate readings and system failure.

4. Controller and Firmware Version: Confirm the controller is compatible with your existing test systems. The firmware should be at least version 2.3. Older versions may not support modern communication protocols.

5. Calibration and Documentation: Ensure the unit comes with a valid calibration certificate and user manual. Lack of documentation can lead to extended setup times and potential compliance issues.

Failing to perform these checks can result in a unit that requires immediate repair or replacement, costing upwards of $6,000 in the first month of operation.

FAQ

Q: Can I use the 3350-CA with a Keysight 34980A?
A: No. The 3350-CA is not compatible with the Keysight 34980A due to communication protocol differences. Attempting to use them together can result in system errors and potential damage.

Q: Should I buy a 3350-CA with over 12,000 thermal cycles?
A: It’s not recommended. Units with more than 12,000 cycles typically require more frequent maintenance and are more prone to failure. A new heating element can cost $1,200–$1,500.

Q: How long can a 3350-CA last with proper maintenance?
A: With regular calibration and component replacement, a 3350-CA can last 8–10 years. Units over 10 years old may need more frequent servicing, increasing annual maintenance costs by $1,000–$2,000.

Q: What is the difference in cost between a used and new 3350-CA?
A: A new 3350-CA can cost $24,000, while a used unit in good condition typically ranges from $9,000–$9,500. This represents a 40–60% cost savings.

Q: What test methods should I use to evaluate a used 3350-CA?
A: Perform a thermal performance test and a PID controller response test. The furnace should stabilize within ±1°C at 1,000°C. A deviation beyond ±2°C indicates potential issues.
