Switch-Contact-Actuated Hour Meters

These meters do not require voltage to register a count.

Panel-Mount Electrically Actuated Hour Meters

Slot these counters into a control or electrical panel cutout.

Electrically Actuated Hour Meters with Output Relay

Send a signal to another device when the counter reaches a set point. The signal can start/stop a process or trigger an alarm.

Vibration-Actuated Hour Meters

Record the running time of machines and vehicles that vibrate while operating.

Electric-Motor-Actuated Hour Meters

With a sensor that’s activated by your electric motor’s magnetic field, these meters show the motor’s running time.

Preventative Maintenance and Inspection Indicators

Mount these indicators to your equipment, and their bright LED will catch your attention when it’s time for maintenance or inspection.

DIN-Panel Cutout Adapters

Use these adapters when the size of a meter face is too small for the DIN cutout in a panel or enclosure.

Timing

Multifunction Smartwatches

Keep your phone in your pocket and your hands free—these smartwatches perform a variety of functions on your wrist.

Timers

Count down to zero or count up to as much as 24 hours with these digital timers.

Metal- and X-Ray-Detectable Stopwatches

Track time on food processing lines while reducing the risk of contaminating the food. To help you comply with Hazard Analysis and Critical Control Point (HACCP) programs, these plastic stopwatches contain metal and chemical additives that will set off metal detectors and show up on X-ray machines.

Stopwatches

Quickly view starts and finishes on a digital screen.

Combination Wristwatch/Weather Monitors

Monitor your environment when working outdoors. These wristwatches display time, date, temperature, barometric pressure, and altitude.

Air Particle Counters

Check your indoor air quality (IAQ) by measuring the amount of particles present. These counters are often used to monitor dust levels in workshops, check for particles in classrooms, and measure filter efficiency in HVAC systems.

Handheld GPS Navigators

Navigate on foot with real-time GPS data.

Single Function Chemisty Meters

Remote-Reading pH Meters

The remote sensor with a cable lets you take pH readings in hard-to-reach areas.

pH Meters

More precise than test strips, this meter is often used to measure the pH of dirty liquids in agricultural systems, aquaculture tanks, and printing fountains.

Water-Resistant pH Meters

Check pH in harsh field conditions. These floating meters that have a housing that meets IP67 for complete resistance to dust and protection from temporary submersion.

Water-Resistant ORP Meters

Since this oxidation reduction potential (ORP) meter has a housing that meets IP67 for complete resistance to dust and protection from temporary submersion, it’s often used to determine a solution’s ability to break down contaminants in harsh field conditions.

Water-Resistant Dissolved Oxygen Meters

Check the oxygen levels of water and other clean liquids in harsh field conditions. This meter has a housing that meets IP67 for complete resistance to dust and protection from temporary submersion.

Water-Resistant TDS Meters

Since these meters float and have a housing that meets IP67, they won’t be damaged by temporary submersion and have complete resistance to dust. They detect total dissolved solids (TDS) in water, hydroponic solutions, and other clean liquids to determine contaminant levels.
