Martel BETA DPC300A is with full digital precision and accuracy, a dual pressure system and a built-in loop calibrator function, it’s a pressure calibration powerhouse in a portable format. The internal pump goes up to 300 psi with push-button ease. Exact values are set using the fine vernier control knob. Plant air, up to 100 psi is controlled with a precision regulator for low inches of water on up. DPC300A has a built-in loop calibrator with 24 VDC instrument loop power supply; high capacity rechargeable NiMH batteries for 50 hours of use or 125 cycles of pumping to 300 psi, Martel’s trademark 3 key function menus, ClearBrite™ LCD display and multimode operation to name a few. This high performance calibrator comes in a high performance housing. It’s a rugged IP67 rated blown resin case that can take a pounding when used in the field. IP67 means waterproof including immersion when the case is closed.
