Technical Specifications Temperature and Humidity Chamber

DLA Product Test Center, TA Lab

Objective:

To obtain a Temperature and Humidity Chamber to be used for testing materials subjected to dynamic conditions over time. Currently, the Product Test Center (PTC) has a chamber that is nearly 20 years old and is no longer capable of achieving required testing parameters. This model chamber is no longer manufactured, and repairs are not as cost effective as a complete replacement.

Procurement of a Temperature and Humidity Chamber will enable the Product Test Center (PTC) to regain the capability of subjecting test specimens to stable environmental conditions for leather, paper, and textile materials designated for testing, which will allow the DLA Product Test Center in continuing its mission in providing high quality reporting to its customers.

The DLA Product Test Center-TA Lab has listed the requirements for the procurement of a Temperature and Humidity Chamber. The following specifications are a list of minimum functions and features required by the DLA Product Test Center.

Minimum Requirements:

d) Interior construction: Stainless steel

e) Temperature range: 20°C – 60°C

f) Humidity range: 20%-80%Rh

1. Compatibility - Humidification system must be compatible with Reverse Osmosis (RO) water and must accept a direct plumbed RO water supply

g) Programmable controller: LED display, data logging, adjustable temperature and humidity with ramp and soak function, USB data port, RS-485 communication (MODBUS-RTU), battery backup, and alarm indication of hi/low temp & Rh, and power failure

h) Casters: Equipped with caster wheels

i) Doors: Two hinged, clear view glass doors

j) Shelves: Minimum supplied six (6), adjustable, removable
