SmartBlinky™ Tray Monitor

It is a common occurrence for forklift battery trays to become damaged due to battery electrolyte in the tray. Common causes are run off during battery cleaning, or overflow (boil over) due to over topping of the battery cells.

Once there the electrolyte is hard to detect and hard to remove, with the outcome being a corroded forklift battery tray. This is where the Philadelphia Scientific SmartBlinky Tray Monitor comes in!

The SmartBlinky forklift battery tray monitor alerts the operator if it detects electrolyte in the tray, allowing the removal of the liquid before it causes any damage. The Tray Monitor is a simple, yet highly cost effective way of preventing damage to forklift battery trays.

  • Super bright red and green LED
