Each TruLine ISE features an integrated reference

• 4 sensor technologies - gas sensing, polymer/PVC membrane, solid state, and glass sensor
• Integrated reference (combination/full-cell), BNC connection, connects to any instrument with BNC connectors including the YSI TruLab 1320 or the YSI MultiLab 4010-2 and 4010-3 when used with a BNC adapter,3 foot cable, Made in the U.S.A
• Reference/electrode fill solution, ionic strength adjustor (ISA), and small bottle of standard included with each ISE
• Complete suite of fill solutions, ISAs, and standards available to support customers after purchase
• Applications: Wastewater, environmental, industrial, food and beverage

There are 15 electrodes in the TruLine ISE series, with each electrode measuring the effective ion concentration of a different ionic species. This provides our customer with a wide range of ISEs to choose from. ISE parameters include: Ammonia, ammonium, bromide, cadmium, calcium, chloride, copper, cyanide, fluoride, iodide, lead, nitrate, potassium, silver/sulfide, and sodium. Features replaceable/refillable membrane modules (1 replacement included), pH sensor inside. The TruLine Ammonium laboratory electrode kit includes a PVC membrane combination ISE with replaceable sensor module and refillable reference, bottle of fill solution (30 mL), bottle of ISA (30 mL), and small bottle (30 mL) of high (1000 mg/L) standard. 12 month warranty for solid state, glass sensor, and gas-sensing ISEs, 9 month warranty for ISEs with polymer/PVC membrane.

This eliminates the need for a separate reference half-cell when measuring ion concentration and is more convenient. Each ISE can be refilled with reference/electrode filling solution, extending the life of each ISE.
