Quartz Constant Temperature Bath
 The Modutek Qa Series of Constant
Temperature Baths are the result of almost 20 years of evolutionary
bath design and a passion for establishing the quality and performance
standard in quartz baths. At Modutek, we define quality by the degree
of safety, reliability, and cost of ownership integrated into every
aspect of all our products.
