Martel
Martel Electronics builds documenting process calibrators, and the range here covers general pressure calibrators and pressure modules.
The line is positioned for instrument technicians who need as-found and as-left readings recorded against a procedure rather than simply displayed, which is what turns a measurement into a closed-out work order. Modules are matched to the base instrument, so confirm which Martel calibrator you own before selecting ranges, and check whether you need intrinsically safe certification for the areas you work in.
The Martel Electronics 311A-500CV is a rugged pressure calibrator offering 0.025% F.S. accuracy, a 500 PSI compound range, and multi-function capabilities including RTD and mA measurement. Ideal for field calibration, it features a backlit display, 24V loop power, and supports external pressure modules.
The Martel Electronics 321A EX-30C-3000G is a high-accuracy pressure calibrator designed for demanding industrial applications. With dual isolated sensors, 0.025% F.S. accuracy, and a rugged, explosion-proof case, it’s ideal for gas custody transfer and field calibration.
The Martel Electronics 311A-1500G is a high-accuracy pressure calibrator with a 1500 PSI range and 0.025% F.S. accuracy. It features a rugged design, multiple measurement functions, and supports external pressure modules for versatile calibration in the field.
The Martel Electronics 321A-5CV-15CV is a dual-sensor pressure calibrator with 0.025% FS accuracy, ideal for gas custody transfer. It features two isolated stainless steel sensors (5 PSI and 15 PSI compound), external pressure module support, RTD input, and loop power. Rugged, portable, and NIST-traceable.
The Martel Electronics 311A-30D is a portable pressure calibrator with 30 PSI differential range and 0.025% F.S. accuracy. It measures pressure, RTD temperature, and 4-20 mA signals, and includes a 24 V loop power supply. Ideal for field calibration and gas flow applications.
The Martel Electronics 311A-50CV is a rugged, high-accuracy pressure calibrator with a 50 PSI compound range and 0.025% F.S. accuracy. It measures pressure, temperature (Pt100), and 4-20 mA signals, and includes an internal 24 V loop power supply. Ideal for field calibration and gas flow applications.
