K-1510 Ammonia CHEMets Kit, 0-1 & 1-10 ppm by AquaPhoenix

*Seawater analysis requires A-1501 Stabilizer Solution (sold separately).

Shelf life: Although the Nessler reagent is stable, its high alkali content attacks the glass ampoule. The resulting precipitate interferes with color comparison. The refill has a 5-month shelf life when stored in the dark and at room temperature. This shelf life can be extended by 18 months if the refill is refrigerated.

MGridSet Measurement Grid with Holder by Zarbeco

This Metric Grid has a 10 x 10 Matrix of .7mm x .7mm Squares. One square is further divided into a 10 x 10 Matrix of .07mm Squares. The Grid Line Widths are .001"± .0001" (.025mm±.0025mm).

The Pattern can be in direct contact with the object to be measured. The MGrid can be used to calibrate your MiScope or digital microscope. The holder can be used to raise your MiScope to be even with the MGrid when calibration of a flat object (like paper).

The Reticle Pattern is very durable, double layer, deposited evaporative Chrome/Chrome Oxide, for a reflectivity of less than 5% looking at the pattern. The Patterns on all Reticles manufactured are replicated from Precision Chrome on Glass Tooling under clean room conditions.

Features

• Accurate reference pattern for precise calibration
