Air Operated Portable Calibration Laboratory - Commercial Diving

The Ashford Instrumentation Portable Calibration Laboratory is ideal for the commercial diving market and is suitable for calibrating pneumo and pressure gauges from 10 Meters Sea Water to 400 Meters Sea Water (higher and lower ranges optionally available).  The kit includes everything need to calibrate pressure gauges, pneumo gauges and caisson gauges, we can even help by providing the necessary calculations to different sea water specific gravities which is something that is often overlooked.

The kit comprises:

SPMK 700 Digital Test Gauges With Accuracy 0.025% Full Scale

SPMK 213H Pneumatic Portable Bench Mounted Comparator Pump

BSP & NPT Stainless Steel Adaptors

High Pressure Gas Connection Pipe (For In Situ Testing)

Robust Aluminium Carry Case

The SPMK Digital Test Gauge has a nominal 120mm diameter and features an easy to read backlit display. The The push button display can be scaled in Pa, kPa, MPa, mmHg, kfg/cm2, cmH2O, mmH2O, PSI, Mbar & Bar values. Supplied with a high accuracy of 0.025% FS, the SPMK 700 test gauges can be selected based on the measuring range of the pneumo gauge under test. Each SPMK 700 test gauge can be used to calibrate a range of pneumo gauges as follows:  

Range 0-2.5 Bar - Suitable For Pneumo Gauges (Accuracy 0.25%) from 0-10 to 0-25 MSW

Range 0-6 Bar - Suitable For Pneumo Gauges (Accuracy 0.25%) from 0-24 to 0-60 MSW

Range 0-10 Bar - Suitable For Pneumo Gauges (Accuracy 0.25%) from 0-40 to 0-100 MSW

Range 0-16 Bar - Suitable For Pneumo Gauges (Accuracy 0.25%) from 0-70 MSW to 0-160 MSW

Range 0-25 Bar - Suitable For Pneumo Gauges (Accuracy 0.25%) from 0-100 to 0-250 MSW

Range 0-40 Bar - Suitable For Pneumo Gauges (Accuracy 0.25%) from 0-160 to 400 MSW

The SPMK213H Portable Low Pressure Comparator is a hand operated pneumatic pressure test pump is designed to generate pressures from 95% vacuum to 40 bar (600psi).

Two hand-tight quick connectors installed on the pump allow easy connecting and disconnecting to the test pump without the need for PTFE tape or wrenches. The SPMK213H is an ideal comparison test pump for calibrating pressure measuring instruments such as test gauges, indicators or transducers in the field or laboratory.
