The Myron Ultrameter II multi-parameter meters are fully waterproof, accurate and reliable
Incredibly easy to use: fill the cell cup, push the parameter key and take the reading
Accuracy at ±1% of reading (not just full scale)
Memory capacity of 100 readings
Battery life better than 100 hours
The IP67 rated Ultrameters are waterproof and buoyant and can be fully immersed to 1 metre.
The advanced four-electrode cell for conductivity/resistivity/TDS eliminates polarization, allowing greater accuracy and stability with minimal maintenance.
New features on the 6Pfce
Free chlorine measurement from ORP mV to ppm Chlorine conversion.
Optional Wireless PC communication with bluDock optional accessory
pH calibration on the meter is performed at either two or three points. You should calibrate with pH 7 buffer first then followed by either pH 4 and/or pH 10 buffers. The recommended frequency of calibration of pH is every 2 weeks.
ORP
ORP calibration with the ultrameter is not necessary. Due to the hazardous nature of ORP chemical standards, the ultrameter features an inbuilt electrical calibration. Frequency: Never.
Conductivity (& Resistivity and TDS)
The meter itself measures conductivity and from this reading it can calculate TDS (using a curve of results) and resistivity (the reciprocal of conductivity).There are three chemical standards that can be used and this ensures accuracy across different application types. The most appropriate depends on the composition type of your sample and the parameter you are wanting a result for. The following standards are used:
442 - For use when measuring resistivity boiler and cooling water, lakes, wells etc. Recommended standard - 442-3000
NaCl - For use when measuring TDS of seawater or brackish water. Recommended standard - NACL-14.0
KCl - for use when measuring conductivity directly. Recommended standard - KCL-7000
Recommended frequency: monthly.
Free Chlorine
Free chlorine is not measured directly, rather calculated using ORP, pH and temperature measurements. Frequency - Every 2 weeks (pH).
