Hygiena CalCheck is a reusable LED device for checking that your Hygiena luminometer is reading correctly. Insert it into the luminometer like a test swab and run a negative check (no light) and a positive check (a controlled green LED flash). If both readings fall within the expected ranges, the instrument is working within specification. It takes about a minute and gives your ATP program documented proof that the luminometer can be trusted.
CalCheck is powered by a replaceable coin battery and can be used repeatedly, at whatever interval your quality procedures set, such as weekly or monthly. On the EnSURE Touch, results are saved automatically and sync to SureTrend. The Hygiena CalCheck is available in Canada from Cambridge Environmental Products with CAD pricing and Canadian purchasing support.
A negative check confirms there's no light leak or background error, and a positive check confirms the sensor reads a known light source correctly. You don't need to send the instrument away or use reagents.
CalCheck uses an LED rather than chemicals, so there are no consumables to buy for each check. Only the coin battery needs replacing.
The power button glows green when CalCheck is ready to read, and red, or not at all, when it needs a rest or a new battery.
The EnSURE Touch has a calibration app that guides you through the internal LED, negative and positive checks. It saves the results and syncs them to SureTrend when the instrument is on Wi-Fi.
Steps are from the Hygiena CalCheck instructions. Wait 2 minutes between positive readings.
| Test | EnSURE Touch | SystemSURE Plus |
|---|---|---|
| Internal LED | Above 500 RLU | Not applicable |
| Negative | 0–4 RLU | 0–4 RLU |
| Positive | 255–345 RLU | 40–80 RLU, or within ±20% of your initial reading |
Per the Hygiena CalCheck instructions. If results are out of range, clean the CalCheck rod with alcohol on a lint-free cloth and clean the luminometer read chamber, then repeat. Contact Hygiena support if the problem continues.
