Description

HI is a 2-in-1 pH and conductivity controller engineered for dosage of fertilizer solutions in hydroponics. Two pumps or electro-valves can be wired directly to the controller and be powered through the terminal. The operator can adjust two independent proportional settings for pH and conductivity. The alarm goes off if the pH and/or conductivity are not corrected within the operator-determined time frame of 1 to 10 minutes. The alarm can be turned off during maintenance. The fertilization status can be ascertained from a distance through dosage and alarm LED's.

Features

• Range is 0.00 to 14.00 pH
• Two-in-one pH
• Two separate points can be user adjusted
• Provides for two ground probes, to avoid electrical noise and interference
• Two pumps or electro-valves can be wired directly to the controller and be powered through the terminal

Description

The Sentinel Digital Intelligent Lighting Controller-2's 24-hour digital timer controls two devices, and has a battery backup to remember settings in case of power failure. Controlled devices can be staggered up to 20 minutes apart to allow a single light or bank of lights to reach full intensity before the next is ignited. This unit also features temperature failsafe, shutting down lights if its four-meter remote temperature probe senses that the user-determined threshold has been exceeded. To further protect expensive lighting systems, a user-adjustable "hot start" delay allows ballasts and expensive lamps to cool off for up to one hour if power is interrupted during a lighting cycle. Protected by 3-year manufacturer's warranty.
