To alert you of temperature fluctuations, these recorders sound an alarm and flash the display when temperature rises above or falls below the programmable temperature range. They have a thermocouple type-K probe on a 4-ft. cable for taking readings in hard-to-access areas.

Note: Thermocouple probes are not interchangeable with RTD probes.

Track ambient temperature and relative humidity over time with this recorder. Recorders come with a replaceable sensor, so no probe is needed.

Tally each time you make a pen mark to keep an accurate count. These counters have a black marker that you can replace with a standard permanent marker. Swap the pen with the hand-tally adapter to use these as standard hand-held counters.

These pens are pressurized to write at any angle, on wet surfaces, and in extreme cold.

Includes four fine round-tip markers (black, blue, green, and red), eight medium chisel-tip markers (black, blue, brown, green, orange, purple, red, and light green), an eraser, and cleaner. All markers are low odor.

Includes a set of four colors. Two different tip widths on a single marker give you versatility. Ink markers work best on clean surfaces.

Choose only the colors you need. Two different tip widths on a single marker give you versatility. Ink markers work best on clean surfaces.

Make marks on natural and synthetic fabric.

This pen writes in black, blue, green, and red ink.

Includes blue, green, orange, pink, and yellow highlighters. They make fluorescent marks that draw attention to text and won't bleed through paper.

Choose only the colors you need. These long-life markers hold more ink than our standard ink markers. They work best on clean surfaces.

An aluminum valve eliminates the risk of seepage caused by the expansion and contraction of a marker due to extreme temperature fluctuations. These ink markers work best on clean surfaces.

Load this marker with a color of your choice and fill up again when the ink runs out. You can change color by swapping out the ink and tip. Ink sold separately. These markers work best on clean surfaces.

Remotely record temperature, humidity, and dew point up to 10 feet from the display and set the alarm to sound and flash the display if temperature readings rise above or fall below a set range. This recorder has a remote probe on a 10-ft. cable and a display that can be set to show current temperature, minimum/maximum temperature, or relative humidity and calculated dew point.

Write on glass, metal, paper, and wood with marks that won't smear or wash off with water, but can be wiped away with a dry cloth or sanding.

Choose the colors you need.

You can leave the cap off of these markers for up to two weeks without them drying out. They work best on clean surfaces.

Choose only the colors you need. These highlighters make fluorescent marks that draw attention to text and won't bleed through paper.

The round sponge tip allows you to apply large, clear marks with ease—even on moving objects such as boxes on a conveyor. These markers work best on clean surfaces.

Record temperature in hard-to-access areas. These recorders have a remote thermocouple type-J probe on a 15-ft. cable. They include 60 assorted charts with a variety of recording times and temperature ranges.

Note: Thermocouple probes are not interchangeable with RTD probes.

Measure and record pressure on a paper chart to troubleshoot system problems and track important process parameters. Recorders are rated NEMA 4X for protection from dirt, washdowns, and corrosion.
