Martel BetaGauge 321 Dual-Sensor Pressure Calibrator Kit - No Current Cert
Approx. £458.32 ex VAT
Product Overview
The Martel Electronics BetaGauge 321 is a portable dual-sensor pressure calibrator for process-control maintenance, transmitter checking and industrial measurement work. Its design incorporates two isolated pressure sensors and a triple-reading backlit display so technicians can view multiple values during field diagnostics. Model capabilities extend beyond pressure to Pt100 RTD temperature measurement, 4–20mA process-loop current, DC voltage measurement up to 30V and an internal 24V loop supply. The platform also supports compatible BetaPort-P external pressure modules. Manufacturer literature quotes pressure accuracy of 0.025% of full scale for the model; this is a product specification rather than evidence of a current traceable calibration on an individual used instrument. Exact installed sensor pressure ranges should be confirmed from the instrument labels where required.

What You Are Buying
Martel BetaGauge 321 calibrator, hard carrying case, documentation and assorted accessories shown in the product photographs.
Condition & Testing
Refurbished – Very Good. Fully tested and reported in good working condition with minor cosmetic marks and scratches. No current traceable calibration certificate has been verified, and exact installed pressure ranges are not established.
Compatibility
Suitable for pressure and process-calibration work within the capabilities and installed ranges of this specific BetaGauge 321. Confirm required pressure ranges from the physical instrument labels. Buyers needing traceable calibration should arrange current certification separately.
Please Note
No current traceable calibration certificate is supplied. The manufacturer-rated accuracy is a model specification, not proof of current calibration; buyers requiring traceable certification should arrange calibration for their application. Check the instrument labels for the installed pressure-sensor ranges.
Shipping, Warranty & Support
Held in our UK stock and securely packaged for dispatch using the delivery service shown at checkout.
This product is supplied with a 12-month Pro-AVIT warranty for its tested working condition. Calibration certification is separate from the functional warranty. Our UK-based team can assist with product questions before or after purchase.
