Calibration Options

A calibration service can be purchased for this unit. Once the Service has been performed a certificate of calibration is produced and dispatched with your order. Calibration Services are performed on receipt of your order and as such will delay shipping. Details and options are outlined below.

Traceable Calibration (Temperature / Humidity) Price
Issued at 4 points: 20°C & 30°C (Temp)
35% & 75% @ 20°C (Humidity)		 £80.00
Additional points available from: From 0°C to 50°C
From 30% to 95%RH		 £5.00 (Temp)
£15.00 (Humidity)
Traceable certification is adequate for most applications and meets the calibration requirements of ISO 9001. All measurements contained in this type of certification are traceable back to National UKAS Standards.
Traceable Calibration (Temperature / Humidity) Price
Issued at 5 points: 2 x Temp; 20°C & 30°C (Temp)
3 x %RH; 35%, 55% & 75% @ 20°C 		£88.00
Additional points available from: From 0°C to 50°C
From 30% to 95%RH		 £5.00 (Temp)
£15.00 (Humidity)
Traceable certification is adequate for most applications and meets the calibration requirements of ISO 9001. All measurements contained in this type of certification are traceable back to National UKAS Standards.
UKAS Calibration (Temperature / Humidity) Price
Issued at 4 points: 20°C & 30°C (Temp)
35% & 75% @ 20°C (Humidity)		 £116.40
Additional points available from: 5°C to 50°C / 25% to 95%RH £10.00 (Temp)
£25.00 (Humidity)

A UKAS calibration can also be considered traceable. The difference between the two is that UKAS calibrations are carried out under the remit of an ISO/IEC 17025 quality system by a laboratory that has been accredited by UKAS, to ensure the consistency and accuracy of results.
