Pocket pH Meter

For the accurate measurement of pH in seconds.

HORIBA's unique compact meter integrates the electrode, display and sample container to enable simple, effective on-site testing by direct measurement from a single drop or sample immersion. 

Urine pH will vary according to species, breed, diet and health status. 

Measurement of urine pH in cattle has shown to be a good indicator of metabolic status and helpful in managing the risk of clinical or subclinical hypocalcaemia.  Dietary manipulation should be undertaken in conjunction with careful urine pH monitoring. 

In pets, accurate assessment of urine pH is a key part of urolithiasis management and can aid in preventing the recurrence of urinary crystals or stones.

The only pocket meter that directly measures pH in 0.1ml sample (or 0.05ml sample with sampling sheet B). Unique sensor allows measurement of viscous liquids, solids, and even powder samples. No need for a beaker to calibrate your meter or measure a sample. Just place few drops of the standard or sample onto the flat sensor. This procedure saves you time and prevents wasting your precious sample.
