2359300 Molybdenum Test: Hach Color Disc Low Range by AquaPhoenix

Molybdates are used to inhibit corrosion in industrial and utility water systems. The high cost of these treatments warrant careful control of their concentration. Kit reagents react with molybdate to form a blue color, which is measured with a color disc.

• Easy-to-use Color Disc
• Effectively Monitors Corrosion Inhibitors

Includes two reagents, one color comparator box, one color disc, two stoppers, instructions, and a carrying case.

SXL-DVX1 Drain System with Valve by Agrowtek

Electronic optical "liquid level control system" includes two liquid sensors for high and low "fill" or "drain" control of fluids in tanks, reservoirs, etc. Only power and a valve or relay is required to complete the level control system; no external controller required. Easy to wire and setup. Includes one standard and one latching sensor. Compatible with 5-24Vdc valves and relays. Available with optional VX1 water valve kit or RX1 outlet kit for direct operation of 120Vac pumps, valves and other equipment.

91210-03 Traceable Dual-Input/Output Thermocouple Thermometer with RS-232 and Calibration by Digi-Sense

Serial computer output allows thermometer to be connected to computer or data logger for capturing and storing results. Resolution is 0.1° (from -50.0 to 199.9°F) and 1° in both °C and °F over the entire range of -50 to 1999°F or -50 to 1230°C. Meter only accuracy is ±0.75% + 1°C. Memory recalls maximum and minimum readings. HOLD button freezes display for reading later. Dual channels permit monitoring two separate probes. Dual display simultaneously shows temperature of both probes or temperature of one probe and the difference between probes (T1-T2).

Supplied with two probes and case. Case is impact-resistant ABS plastic. Uses all Type-K thermocouple probes.

Traceable® Products have an individually-numbered Traceable® Certificate provided with each unit, that assures accuracy from our ISO/IEC 17025:2017(1750.01) calibration laboratory accredited by A2LA. It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement. Each product goes through an intense vetting process before it can carry the Traceable name, thus saving you both time and money by not having to calibrate separately.

• Includes NIST-Traceable certificate from our A2LA accredited (1750.01) calibration laboratory
• Max/min temperature readings
• Uses all Type-K probes

Includes

two probes, 48" cable, 9-volt battery, and NIST-traceable calibration certificate with data.
