Hello all. I am looking to purchase a datalogger that can measure surface temperatures of frozen fish. Would you please share your experiences and recommended manufacturers and/or models. Thank you

You can get flat probes which are ideally put between two items.  I can't say I've got much experience with them but my team did without seemingly having an issue.  It is probably good practice to validate what kind of core temperature a surface probe will relate to but it might not be necessary for your product.

 

Here are a few options:

 

Foil between pack temperature probe

Comark SX23L Between Pack Food Probe (1 Mtr Cable) -40°C to +70°C - Thermometer Point

Hanna HI-765BP/G Between Pack Probe | Thermometer Point

 

There are other options with more "pointy" ends but I'd recommend getting a flexible one to avoid someone being tempted to try probing the fish.

Hi The Prof,

 

Hope things are okay with you.

 

I have used Comark data loggers previously and they were very good. You can programme multiple loggers as you only need one station to programme them. I have used them to monitor/record temperature on a fleet of delivery vehicles in the past.

 

I think they are being phased out in favour of wifi data loggers but you can still buy them:

Other brands are sold at RS but I haven't used anything else other than Comark for a long time.

 

Kind regards,

 

Tony

Monitoring frozen fish temperature is critical to maintain quality and food safety. Surface temperature dataloggers track fluctuations during storage and transport, ensuring products remain below -18°C as required by global standards. Modern loggers offer real-time data, alarms, and cloud access, helping detect cold-chain breaks early. They’re essential for export compliance, shelf-life assurance, and regulatory audits.
