Systems Analysis & Commissioning Instruments

Building Energy Sciences maintains an inventory of accurate, calibrated testing instruments for use in performing analysis of building systems and for commissioning of building systems. Below is a partial inventory of the quality test instruments used on our projects:                                          (we possess multiple of many of the instruments shown below)

Instrument Inventory

INSTRUMENT: FLUKE 975 Airmeter

MEASURES:

air temperature, relative humidity, carbon monoxide, carbon dioxide, air velocity
