K-1513 Ammonia Vacu-vials® (0-10.00 ppm & 0-150 ppm) by AquaPhoenix

The K-1513 Ammonia Vacu-vials® Test Kit (Nesslerization) comes in a cardboard box and contains everything needed to perform 30 tests: thirty Vacu-vials® ampoules, Stabilizer Solution, 25 mL sample cup, 3-mL syringe, ampoule blank, and instructions. Ammonia concentrations between 10 and 150 ppm can be determined using the 3-mL syringe and dilution instructions included.

This kit requires the use of the V-2000 or V-3000 Photometer, an A-2024 SAM Photometer, or a spectrophotometer capable of accepting a 13 mm diameter round cell. Instrument sold separately.

This test kit can be used to measure the concentration of ammonia in seawater or saltwater by using the A-1503 Accessory Solution Pack (sold separately).

K-1513 is offered as an alternative to the discontinued K-1503. K-1513 offers the same Nesslerization method, but with a modified testing procedure to allow for wider measuring range and longer shelf-life.

94461-27 Traceable 100-Hour Digital Timer with Calibration by Digi-Sense

Versatile timer features four countdown channels, stopwatch channel, and clock. The countdown channels can be started simultaneously, or started individually depending on your application. When the preset time has elapsed, the timer sounds an audible alarm, flashes "TIME IS UP" message on the display, and begins counting up to indicate elapsed time since alarm.

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

Built-in stand, pocket clip, magnet, one 1.5 V button cell battery, and NIST-traceable calibration certificate with data.
