Mini-Ultra Bath (MUB)

Why Choose the Mini-Ultra Bath?

  • Laboratory Accuracy, Field Versatility: The MUB seamlessly bridges the gap between high-end laboratory calibrations and robust field service needs. Unlike expensive traditional baths, the MUB’s stirred liquid bath technology delivers unmatched uniformity and accuracy, wherever your work takes you.
  • Unrivaled Performance at a Fraction of the Cost: Achieve accuracies and uniformities surpassing 20mK, rivaling large floor model baths, all at a fraction of their cost. The MUB is the clear winner for professionals who value precision and budget-friendliness.
  • Wide Temperature Range: The EDL MUB-20130 operates from -20°C up to 130°C, making it ideal for a variety of applications — from chilling to key sterilization testing at 121°C. It’s your go-to calibrator for both cold and mid-temperature needs.
  • Perfect for All Sensor Types: Designed for versatility, the MUB excels at calibrating thermocouples, SPRTs, thermistors, and liquid-in-glass thermometers, both in the lab and in the field. Its deep well accommodates almost any immersion-style sensor with minimal fit and immersion errors.

Engineered for Precision and Convenience

  • Stirred Silicone Oil Bath: The MUB utilizes silicone oil as the stirred liquid medium (available directly from EDL), ensuring stable and repeatable results across the entire temperature range.
  • Uniquely Deep Well Design: Engineered to reduce fit and immersion errors, the uniquely deep well accommodates various sensor types and lengths, giving you flexibility and confidence in every calibration.
  • Sensor Support System: Each unit includes a sensor holder (expandable to as many as your workflow demands), the MUB-Sensor Support Pole, Sensor Holder Clip, and additional holders as needed — simplifying testing multiple sensors at once and streamlining your operational efficiency.

State-of-the-Art Control and Connectivity

  • Advanced Controller: The MUB features a premium, pre-programmed controller delivering superb accuracy and repeatability, so you can trust your results every time.
  • Full Digital Integration: Equipped with an RS-232 interface and supplied i-Tools software, the MUB offers easy connection to your laptop or PC. Enjoy full-function programming, real-time monitoring, and graphing with open-architecture flexibility — empower your quality control with data you can trust and manage with ease.

Quality, Durability, and Peace of Mind

  • Handcrafted in the USA: Every MUB is meticulously assembled in our American facility, ensuring premium build quality, reliability, and local support you can count on.
  • High Strength Aluminum Tank: Rugged yet lightweight, the aluminum tank is engineered for years of dependable use in the most demanding environments.
  • Transport-Ready: A sealable lid ensures safe and spill-free transport so that you can move your calibration setup with confidence.
