Description
All Myron L/controllers feature a highly refined and precise Temperature Compensation Circuit. This feature perfectly matches the NERNST equation correcting the displayed reading to 25°C. The TC may be disabled to conform with USP requirements. Built-in electronic calibration allows for fast quality checks without standard solutions. For maximum system accuracy, buffers are recommended. A push-to-test button makes set point checks easy, while the internal alarm set discourages unauthorized adjustments. Standard on all controller models is a heavy-duty 10 amp output relay, operating on either increasing or decreasing reading. Bright green/red LEDs indicate above or below-set point readings. All 720 Series II models feature an IP65/NEMA 4X water-resistant and corrosion-proof rated enclosure. Compact in size at 6″ x 4.8″, they are suitable for panel, bench, or surface mounting.
