Product Description
Marine labs, aquarists and aquaculture operations get precise salinity numbers without squinting at a scale line. This digital refractometer reports salinity, chlorinity, specific gravity and refractive index on a large LCD, and automatic temperature compensation keeps results consistent from indoor tanks to outdoor ponds and coastal sampling sites.
This listing is for catalog number 48202: Digital Refractometer, MDX-202, Seawater/Salinity, 4 scales. Zero with distilled water, place the sample in the stainless steel prism well and press to measure; the reading uses a 589.3 nm LED source. A continuous mode records 15 consecutive readings, and the sensing unit is IP67 rated for wet conditions. The grip and prism cover remove for cleaning, and a hard case, pipette, AAA battery and manual come in the box. LIGHT LABS ships genuine Heathrow Scientific products with knowledgeable support from our Englewood, Colorado team.
