YSI Palintest Photometer Reagents and Spares

Palintest reagent packs and spares for the YSI 9800 photometer, ordered by parameter in 200 or 250-test packs — ammonia, nitrite-N, nitrate, phosphate, alkalinity, hardness, copper, chlorine, ozone and pH. Running ammonia on a marine system? Add the YAT1707 conditioner, which the saltwater ammonia test requires.

Price range: $30.00 through $340.00 ex GST

YSI Palintest Photometer Reagents and Spares

Product Information

Key Features

  • Palintest reagents matched to the YSI 9800 photometer’s five-wavelength optical system — 430, 465, 530, 575 and 620 nm
  • Covers ammonia, nitrite-N, nitrate, low-range phosphate, total alkalinity, total and calcium hardness, magnesium, sulfate, copper, free chlorine, bromine, ozone and pH
  • Ammonia in saltwater requires the YAT1707 ammonia conditioner (50 tests) — order it alongside the ammonia reagent for any marine system
  • Supplied in 250-test packs for most parameters; nitrate and low-range phosphate come in 200-test packs
  • ±1%T photometric accuracy across both low and high concentration ranges
  • Many parameters follow EPA-approved standard methods for environmental and wastewater testing
  • Spares also stocked: dilution tube (YPT512) and the 20 mL nitrate tube (YPT526) used with the nitrate reagent
  • Choosing your reagents: the photometer is one instrument for every parameter, so you size the purchase by parameter and pack size, not by model. Work out which parameters you test and how often, then order the matching 200 or 250-test pack — and if you run ammonia on a marine system, add the YAT1707 conditioner or the result will be wrong

Frequently Asked Questions

Which instrument are these reagents for?
They are formulated for the YSI 9800 photometer and its five-wavelength optical system. Check with us before using them in any other instrument.
Do I need anything extra to test ammonia in seawater?
Yes. The YAT1707 ammonia conditioner (50 tests) is required with the ammonia test in saltwater – without it the reading will be wrong.
What range and resolution does each parameter cover?
This varies by parameter and is not published on this page. Tell us which parameters you run and we will confirm the range and resolution before you order.
What pack sizes are available?
Most parameters come in 250-test packs; nitrate and low-range phosphate come in 200-test packs, and the ammonia conditioner in 50 tests.
How long do the reagents last?
A shelf life is not published on our source data. Check the expiry date printed on each pack and rotate your stock.
Are the methods standards-approved?
Many of the parameters follow EPA-approved standard methods for environmental and wastewater testing.
Which spares do you stock?
The dilution tube (YPT512) and the 20 mL nitrate tube (YPT526), which is used with the nitrate reagent.
