Lamps / Bulbs (Click for complete details):
Equipment manufacturers don't make the lamps they sell, so why paythe high prices they and their industrial distributors charge? Try our factory-spec replacements for all industrial and scientific applications, including printing, graphic arts, silkscreen, microscopes and illuminators, medical manufacturing, optical comparators, printed circuitboard(PCB)manufacturing and CD replication, medical and scientific equipment.
We also supply a full range of lamps for ultraviolet (UV) curing conveyors and digital presses, tunnels, chambers and spot curing guns, and infrared (IR)/flash drying/heating, germicidal UV, fadeometers, aquariums, LCD projectors and even metal halide general illumination lamps and ballasts for factories and warehouses.
Lamp types include metal halide, mercury vapor, pulsed xenon, quartz halogen, incandescent, ultraviolet (UV) curing, mercury capillary, short arc mercury and xenon, germicidal, fluorescents and infrared (IR).

Digital Meters & Testers for pH and Conductivity (EC and TDS)
by Hanna Instruments (Click for complete details):
pH meters measure acidity and alkalinity of any liquid, including printer's fountain solution and CTP chemistry, for water and soil testing, aquariums, hydroponic gardening and other applications.

Conductivity meters measure EC (electrical conductivity), TDS (total dissolved solids) and solution strength.

Our new combination meters read both conductivity and pH. The HI98129 and HI98130 combo pocket versions are waterproof and also read temperature, for less than the cost of two individual meters! The HI9811-5 is a hand-held unit that measures pH, EC and TDS with a remote probe.

The HI 98311 / Dist-5 meter is waterproof and reads EC, TDS, and temperature.
HI 98127 / pHep-4 and HI 98128 / pHep-5 meters are waterproof and read both pH and temperature.

BRAND NEW!! The HI991404 GroChek indicator provides continuous monitoring of pH, conductivity (EC or TDS) and temperature, while the HI991401 GroChek indicator provides continuous monitoring of pH and temeperature.

HI98510 measures Fahrenheit
HI98509 measures Centigrade

Measuring Instruments for Thickness, Hardness, Lines/Inch and Stainless Steel Rulers (Line Gages) (Click for complete details):
Digital and analog thickness gages measure paper, plastics, wood, metal, and other solid materials.
Digital micrometers (mechanical and electronic versions) have visual readouts for ease of use and ratchet mechanisms to measure compressible materials.
The Truetest Durometer checks the hardness of compressible materials, including printing-press rollers and silkscreen squeegees.
Screen finders/mesh counters determine the lines or threads per inch in any regular repeating pattern up to 250/inch.
Stainless steel line gages with scales in inches, picas, metric and points.

Anti-Moiré/Anti-Aliasing Filters for Electronic Cameras (Click for complete details):
These brand-new optical filters are used in front of the lens by digital photographers to eliminate pattern moiré and aliasing ("Christmas Tree light" effect) when making the shot, so there is no need for electronic re-touching.
