Instrument enclosures are commonly used to protect instrumentation against adverse weather conditions or physical damage and to ensure that the instrument operates at the proper temperature range. However, enclosures may not always provide sufficient protection against the temperature extremes that can affect instrument performance. Temperatures that are too high, for example, can cause fluids to vaporize. Temperatures that are too low can cause some lines to freeze or some products to thicken – resulting in damages to sensitive equipment.

For many instruments, the correct temperature of the instrument and sample will affect measurement accuracy. The best way to solve this problem is to equip enclosures with systems designed to maintain interior temperature within the range specified for optimal performance.
