90433-91 Thermowell, 304 Stainless Steel, 18" Length, 3/4" Connection by Digi-Sense

To match your probe to a thermowell, first measure the distance from the probe's tip to the top of the thread (typical thread length is 0.5" for 1/2" NPT fittings). Next, match this length to the probe depth of the thermowell ("A" dimension). Other thermowell sizes and materials are available - call our Application Specialists for more information.

• Limited-Space Thermowell when you need a shorter insertion depth.
• Standard Thermowell for general-purpose applications.
• Heavy-Duty Thermowell for higher fluid velocity ratings.

93423 X-Cel LX 9mm Eyepiece by Celestron

Celestron X-Cel LX series eyepieces offer a 60° apparent field of view, perfect for the Moon, the planets, and a plethora of deep-sky objects. The premium six-element optical set is finished with multiple layers of high-transmission coatings for clear, sharp images. The edges of the optics are blackened for increased contrast. All seven X-Cel LX eyepieces sport 16 mm of comfortable eye relief, and are parfocal, which means you can switch out eyepieces within the series during observing sessions and little or no additional focusing will be required.

The X-Cel LX eyepiece body is made of black-anodized aluminum. The pop-up eyecups make it easy to adjust the height for different users. Turn them in one direction to extend the length, and the other direction to provide a flat surface, preferable to most eyeglass wearers. A treaded rubber grip around the center of the eyepiece barrel offers secure handling, even in moist conditions or with heavy gloves on. The 1.25" insert barrel is threaded to accept filters.

• X-Cel LX eyepieces, optimized for planetary viewing, offer a 60° field of view through a six-element fully multi-coated lens system.
• Pop-up rubber eyeguards provide comfort and increase contrast. Raise and lower with a simple twist.
• A treaded rubber grip offers a no-slip grip, even with gloves on.
• 1.25" barrels are threaded to accept filters.

K-1520C Ammonia HR CHEMets® Test Kit (1000-10,000 ppm) by AquaPhoenix

The K-1520C Ammonia HR CHEMets® Test Kit (1000-10,000 ppm) comes in a plastic case and contains everything needed to perform 30 tests (except distilled water): 30 HR CHEMets® ampoules, a color comparator, fixed volume pipet, 25 mL sample cup, and instructions.

This kit is applicable for wastewater, environmental, aquaculture or any application where high concentrations of ammonia may be found in water.

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.
