ULTRAPEN PT4 Free Chlorine and Temperature Pen. Save 10% NOW - Now In Stock. Advanced features include highly stable microprocessor-based circuitry; automatic temperature compensation from 15ºC to 30ºC while in calibration mode; user-intuitive design; and waterproof housing. A true one-handed instrument, the PT4 is easy to calibrate and easy to use. To take a measurement, you simply push a button then dip the PT4 in solution. Results display in seconds. Results display in seconds.This instrument is designed to be extremely accurate, fast and simple to use in diverse water quality applications.

The Myron L Company Free Chlorine function reports FAC quickly and accurately by measuring, the chemical characteristic of chlorine that directly reflects its effectivity, cross referenced with pH. Both DPD kits and colorimeters may tell the user the FAC value of the sample in the test tube, but since the chemistry of that sample is quite different from the source water being analyzed, the results are imprecisely related to actual disinfection power. The Myron L Company FCE function measures the real, unaltered chemistry of source water, including moment-to-moment changes in that chemistry.

Standard Solutions for calibration:
The ULTRAPEN™ PT4 requires pH4, pH7, and pH10 pH Buffer Solutions and 80 mV Quinhydrone, 260 mV Quinhydrone, or 470 mV MLC Light's ORP Standard Solutions for wet calibration, and Sensor Storage Solution for proper storage.

Replacement Sensor:
The ULTRAPEN™ PT4 features a user replaceable Free Chlorine sensor. Installation instructions included with sensor.
Order model#: RPT4

Electrode Cleaning Paper:
Routinely cleaning the electrode will keep the sensor free of build-up that can affect the speed and accuracy of readings. Instructions for use are included with the paper.
Order model#s: PH4, PH7, PH10, ORP80, ORP260, ORP470, ORPCALKIT, PHSS
