Use Cases
Hospital & Laboratory Monitoring
Proven in healthcare: O.K. Servis BioPro uses CHESTER Display to monitor environmental conditions across multiple hospitals - clinical staff get local visual alerts at the point of care while records flow to the cloud.
Cold Chain with On-the-Spot Readout
Check cold room and storage conditions right at the door. Staff see current temperatures and alarm states on the spot, while continuous cloud records keep audits covered.
Local Visibility for Facilities
Cleanrooms, production areas, and storage facilities where operators need current conditions visible in the room - one device shows the values everyone needs to see.
Audible Alarm Signalling
When a threshold is crossed, the buzzer sounds where people actually work - no missed emails or silenced phones - and cloud alerts notify the wider team in parallel.
