The OYSTER underwater TEMPERATURE LOGGER
Dec 99 update : see an amazing
lost and found story|
|
|
WHAT IS IT ? |
An electronic temperature recorder about the same size as an oyster and robust enough to be left inside oyster bags. It will record the temperature every 30 minutes for nearly six months. Or every hour for a year. All you have to do is make a note of the date and time of any ‘event’ (such as putting it on site) which you might want to identify later on the temperature graph |
|
WHAT FOR ? |
This logger is designed specifically to measure sea water temperatures. However many other applications are possible: Fish in transit. Fridges. Delivery vans. Cold stores. Incubators. Purification tanks. Broodstock conditioning. Packaging trials...Think about it ! |

SPECIFICATION |
Waterproof to 30metres depth |
|
OUR SERVICE |
We are offering a service where we loan out the loggers and you pay for the rental and production of the temperature graphs. (See example below) We offer a one-trip service up to one month, or six monthly or annual for longer term monitoring . We can arrange to send replacement loggers to arrive before the end of the recording period to ensure uninterrupted data. We can work with lunar months or produce special graphs, such as degree-days, to customers individual requirements. |
|

We aim to offer an efficient service. We will despatch your logger within 7 days of receiving your order. We will post (or fax on request) the temperature graph within 48 hours of return of logger otherwise we will refund the charge. If the logger fails to record for any reason we will provide a free replacement service. Users may return loggers at any time for refund of deposit, subject to £20.00 minimum ‘one-trip’ charge. |
