We are regularly asked how often our products should be calibrated. Unfortunately, there is no definitive answer, as it entirely depends on local, national & industry standards or the level of use of each product. If a transmitter is used heavily in tough environments, with high pressure spikes or vibration, we may suggest that it is calibrated more frequently than a product that has low, light usage.
Usual lead time for re-calibrations is 2 weeks from when we receive the unit.

If an incorrect product has been purchased in error, you may be eligible for a credit provided we are notified and the unit/s is returned within 28 days. A minimum 25% re-stocking fee applies.
