Peak Sensors became our main supplier for thermocouples when our previous main supplier that we had used for over 20 years would no longer fulfil the particular requirements that we had agreed previously. Peak Sensors discussed our requirements and was able to exceed them so they have now been our main supplier for the last two years. We have had no problems with the product that they have supplied to date and all deliveries have been on time. They keep us informed of any possible changes they wish to make to the supply and obtain our approval in advance. We normally receive updated quotations for our standard thermocouples within hours or at latest the same day. An excellent supplier.
