Name Description
Vacuum Gauge Calibration Meet demanding quality standards when you calibrate your vacuum gauge at LACO. Our calibration lab services all types of vacuum gauges including Ionization, Cold Cathode, Pirani, Convection Pirani, Thermocouple, Capacitance Diaphragm, Quartz Sensor, Bourdon Tube, and Capacitance manometers (MKS Baratrons). Operating in compliance to the most recent ISO standards for calibration laboratories, we are independently accredited by A2LA to ISO 17025 and ANSI/NCSL Z540-1994. Our lab follows American Vacuum Society recommended practices and all calibrations are NIST-traceable.
Thermocouple Gauges and Sensors LACO offers both digital and analog thermocouple vacuum gauge displays for use on vacuum measurements from ATM to 10^-3 torr. LACO also stocks the full line of Hastings Thermocouple Gauge Tubes Sensors which are precision sensing devices designed to provide accurate measurement and control of vacuum. Fully compensated for both temperature and rate of temperature change, the tubes are renowned worldwide for their dependability. All Hasting gauge tubes use 1/8" NPT male connections. See LACO's LACO's NW to NPT adaptor for other connection options.
Please inquire about gauge options with relay setpoints, analog outputs, or high accuracy gauges for use as reference standards. All gauges can also be quoted to include NIST traceable and A2LA ISO Guide 17025 calibration certificates.
Vacuum Gauges LACO offers a broad selection of medium-range vacuum gauges including low-cost bourdon tube gauges for relative vacuum readings from 0-30inHg to thermocouple and pirani type absolute vacuum gauges with readings down to 1 micron or 1 millitorr. Please inquire about gauge options with relay setpoints, analog outputs, or high accuracy ion or cold cathode gauges. All gauges can also be quoted to include NIST traceable and A2LA ISO Guide 17025 calibration certificates.
