71013 SkyMaster 15 - 35x70 Zoom by Celestron

Celestron's SkyMaster Series of large aperture binoculars are a phenomenal value for high performance binoculars. Ideal for astronomical viewing or for terrestrial (land) use, especially over long distances. SkyMaster models feature high quality BaK-4 prisms and multi-coated optics for enhanced contrast.

• Lower magnification allows the user to locate a subject more easily and then zoom in for a close-up view
• Multi-coated optics enhances sharpness of detail and crispness of color
• High quality BaK-4 prisms provide higher light transmission for better viewing in low light conditions
• Large objective diameter provides a comfortable viewing aperture at high magnification levels
• Long eye relief for more comfortable for all users; essential for those wearing eyeglasses while viewing
• Diopter adjustment allows for refinement of image to correct for any differences in strength between the users own eyes
• Tripod adapter included to mount the binocular on a tripod for prolonged viewing sessions or simply for increased stability while observing
• Limited Lifetime Warranty

90551-25 Adjustable Angle Bimetal Thermometer, 5" Dial, 24" L, Range 0-250F/-20-120C by Digi-Sense

Accuracy is ±1% full-scale when stem is immersed 2" in liquids or 4" in gases (immerse models with a 2.5" stem length 2" in gases). Measured stem length from the top of the threads to the bottom tip of the stem. Stem dia is 0.25"; threaded connection is 1/2" NPT(M). All thermometers meet or exceed ASME B40.3 standards. Maximum environmental temperature for glass lens thermometers is 500°F (148°C).

• Greater temperature range
• Anti-parallax dial for accurate readings
• Hermetically sealed per ASME B40.3 standard to prevent fogging and protect against tough environments
• Rugged 304 stainless steel construction with a clear glass lens
• Recalibrate using the external reset screw

93831-75 Surface RTD Probe, 100 Ohm, ANSI 3-Blade Connector, 10" L, 5ft Coil Cord by Digi-Sense

Maximum error for probe assembly is ±1.1°C + 0.12% of reading below 300°F, ±0.35% of reading above 300°F. Alpha coefficient is 0.003850 Ω/Ω/°C (DIN IEC 751). Resistance at ice point (0°C) is 100 Ω.

Note: Time constant is the time required to reach 63.2% of the new reading. To determine how long it will take to reach 99% of the new reading multiply the time constant by five.

Note: The temperature range is for the probe tip only. The handle material may be affected if the probe is rated higher than the handle depending on exposure time, application, and handle material. ABS handles are rated to 220°F (104°C); PVC handles are rated to 200°F (93°C); Stainless Steel handles are rated at 450°F (232°C); Mini Connectors are rated to 392°F (200°C).

• Time Constant: 1-3 seconds or greater
• Custom designs or changes to this product are available upon request
