SOTA

The SOTA Laboratory combination pH electrodes feature a molded polymer body with a removable bulb protector to facilitate cleaning. The electrode features the patented porous Teflon® liquid junction, gel filled reference cell with controlled release KCl rings to maintain a stable reference cell potential.

The optional TOP68 quick disconnect cable system provides ease of use and the reliability of fixed cable. The TOP68 has an IP68 environmental rating, which means it's water tight and corrosion resistant, making the electrode suitable for extended measurement in damp, humid or wet conditions.

Model 10 pH Sensor

Model 10 pH Sensor is designed for use in general purpose water applications. The large volume single junction reference cell coupled with the non-fouling porous Teflon® liquid junction assures a long life in general service.

M-11 / M-15 / M-21 / M-17

Model 11 pH sensor features a protective pH electrode guard and provides an insertion length of 23.0mm (0.9"). Sensors with protective guards are recommended to reduce the risk of accidental breakage, or to deflect foreign objects in flowing streams.

The Model 11 process pH sensor features the Plunger pH electrode design which permits 360o sensor mounting. The porous Teflon® liquid junction resists fouling and chemical attack. Double junction reference cells increase the service life in applications containing sulfides (H2S) and metals such as lead, mercury and silver. The new cast-in-place solid reference electrolyte helps maintain a constant reference cell potential by resisting dilution over time with pressure and temperature changes. The new capillary temperature sensor design places the Pt100 or Pt1000 TC behind the pH sensitive membrane for accurate temperature compensation and measurement. The TOP68 quick disconnect cable system provides ease of use and the reliability of fixed cable. The IP68 environmental rating protects the high impedance pH electrode signal from moisture resulting from condensate build up in submersion pipes.

Ion Selective Electrodes

The SENTEK range of standard mono ion selective electrodes are ideal for applications where high accuracy is required, particularly where ion levels are low (<1ppm) Mono and Combination:

Combination

Main features and benefits include:

• No Reference electrode needed
• Available in fully submersible and waterproof format
• Solid state sensors
• Ideal for unskilled operatives
• No filling solution
• Virtually unbreakable
• Can be left dry for long periods
• Long lifetime

Cable length can be specified at the time of ordering. Maximum length is 10 meteres.

Standard products are fitted with 1 metere of cable terminated with a BNC connector. Dimensions: 120 x 12mm.

These electrodes can be used with any conventional laboratory or handheld pH meter with a milli volt mode.
