Test Equity 140 Temperature Chamber

The Test Equity 140 Temperature Chamber stands out in the realm of temperature testing, offering a remarkable full-range temperature capability within the smallest footprint in its class. Building upon the proven technology of the successful Test Equity 1007C, this model presents a compact design at an economical price point, making it a superior choice for various testing requirements.

Key Features

High/Low Temperature Limit Controller and Alarm

The chamber is equipped with a highly functional High/Low Temperature Limit Controller that functions independently to safeguard against extreme temperatures. Users can customize both high and low limits, ensuring the chamber shuts down and activates an audible alarm during any out-of-limit condition. Additionally, the uncommitted contacts provide a safety power interlock for enhanced protection of your test sample.

Innovative Viewing Window

Designed to minimize exterior window sweating during temperature cycling, the unique viewing window not only enhances usability but also aids in maintaining optimal operational conditions.

Access Ports for Connectivity

Featuring two 4" access ports located on both the left and right sides, the Test Equity 140 allows effortless attachment of wires and sensors to your test samples, facilitating a versatile testing setup.

Adjustable Shelving

The heavy-duty stainless steel wire shelf ensures excellent airflow around your test samples, contributing to even temperature distribution for reliable results.

Chamber Condensate Drain

Designed with user convenience in mind, the chamber includes a floor drain for efficient removal of condensate that may form during temperature transitions.

Mobility with Casters

Rugged 3" casters allow for seamless movement of the chamber, making it easy to relocate it as testing requirements change.

Durable Power Supply

Equipped with a heavy-duty power cord featuring a NEMA L6-30P twist-lock plug, the chamber operates on 208V or 230V, 1 PH power supply for reliable performance.

Advanced Refrigeration System

Utilizing non-CFC refrigerants in a dual compressor cascade configuration, the Test Equity 140 optimizes cooling performance across the operational range. Key elements like pressure regulators and liquid injection ensure safe and efficient operation, while sequential compressor starting reduces power demand during startup.

Reliable Electrical Controls

Featuring UL approved electrical components, the chamber ensures safety with class-CC fuse protection for each branch circuit. The nichrome air heater is designed for low watt-density, providing even heat distribution while the fusible link adds an additional layer of thermal runaway protection.

Service Accessibility

Both the side and rear panels of the chamber are removable, granting complete access to the refrigeration system for hassle-free service and preventive maintenance.

Controller Options

The Test Equity 140 can be configured with either the original F4 controller or the advanced F4T touchscreen controller:

• F4 Controller: Supports programming of up to 256 steps within 40 customizable profiles. It includes a four-line backlit LCD for clear display of programming information, actual temperature readings, and alarm notifications.
