We have used this temperature controller for a wide range of industrial applications and couldn't be happier with the results. The temperature control is exceptional and precise making it perfect for scientific AND engineering work. Based on our own experience, it is a reliable and durable piece of equipment that has never let us down. The compact size makes it perfect for transport, and it is intuitive and easy to navigate. The only con we can think of is that it is a bit on the expensive side, but it is well worth the investment for those who require precision temperature control in their work..
