What our customers say

St. Vincents University Hospital
"The Kelsius system has provided reliable temperature monitoring in 90 medication fridges across the hospital and makes 24hr monitoring in all areas possible.

It has ensured rapid response to deviation from recommended temperatures and provided important data about fridges and allows trends to be identified. In the future we hope to expand our monitoring system to include room temperature and humidity monitoring.

The potential maximum financial savings within a three-month period was approximately €120,000 if all stock involved had to be discarded."
Caitriona Reilly & Paul Tighe
Pharmacy Department
Torbay and South Devon Trust
“The Kelsius system has allowed us peace of mind that our fridges and incubators are being monitored in real time and let us know when they deviate from the allowed parameters.

We have installed Kelsius throughout our Pharmaceutical facility to cover all units including ambient monitoring of our Warehouse.

Live and historical Data is available at all times which allows us to cover any inspections and audits carried out.

Follow up service is excellent and an annual service is included.

Highly recommended by our team.”
Dr Alison Webber
Head of Microbiology
Maidstone and Tunbridge Wells
The Kelsius temperature monitoring system meets all our requirements and expectations.

We have Kelsius sensors to record product and air temperature throughout our Pharmacy Dispensing areas, Clinical Trial rooms and Aseptic units where drugs are stored and prepared.

The robust alarm alert system (SMS/e-mail/flashing beacon/audible) allows us to take corrective actions well on time allowing stock to be relocated and thus reducing financial impact of the loss of high value refrigerated products.

Calibration Certificates are traceable to a UKAS Certificate.

With Kelsius in place, we have increased confidence in product quality and patient safety. Moreover the digital temperature monitoring system has already paid for itself since installation by helping save time and reducing product loss."

Forth Valley Royal Hospital
"The actual system is user-friendly and weekly reports, graphs and reports can be accessed and interrogated thoroughly. We have experienced an excellent, proactive and friendly customer service throughout. Kelsius staff are always professional, approachable and keen to assist with any issues, queries or future project work.

Forth Valley was the first site in Scotland to utilise Kelsius. We have recommended Kelsius to other NHS Health Boards and Pharmacies and would continue to do so in the future."
Daniel Kelly
Quality Assurance
"The Kelsius remote sensors provide 24/7 monitoring of our GMP storage areas. Email alerts are sent to staff when temperature/humidity go out of the specified ranges which allows for prompt corrective action. The online system is user friendly and access to sensor data is restricted to staff with passwords. The system generates graphs and reports for easy interpretation of data and calibration information for the sensors on site is readily available on the system which is beneficial during audits

The Kelsius support team are extremely helpful. Queries are always responded to promptly.”
Claudine Kavanagh
Quality Assurance Engineer
Biokinetic Europe
"BioKinetic Europe has been successfully using the Kelsius system since 2011 to monitor the temperature of over 13 refrigerators and freezers and the temperature and humidity of four environments.

The Kelsius system helps to ensure compliance with • 24/7 instant text and email alerts to nominated staff members ensuring that any temperature excursions are dealt with immediately • Ability to set temperature alarm limits • Ability to print out temperature graphs in one click for study files, audit or inspection purposes • A full system audit trail

The portal is extremely user friendly and queries directed to the Kelsius support team are always answered promptly and in a friendly and professional manner. Highly recommended.”
Ashleigh Wilson
Quality Assurance Manager
Central Manchester University Hospitals
"GMIS was the first pathology laboratory in the UK to achieve accreditation to ISO standard 15189 of UKAS. Use of the Kelsius temperature monitoring system strengthened our position and ability to successfully achieve this quality standard.

In the event of a temperature deviation from our defined limits the laboratory personnel are notified immediately and are able to address and rectify any issues. The temperature readings are easily accessible from a central web portal that allows the data to be displayed in the form of tables and graphs, providing a full audit trail that is compliant with UKAS.

The Kelsius system helps financially by ensuring that expensive commercial kits and reagents aren’t lost due to temperature damage and staff time is used more productively in delivering our immunology service."
