MistKing ST-24 Seconds timer

The MistKing ST-24 Seconds Timer is a dedicated misting controller built exclusively for use with MistKing misting systems. Designed for reptile and amphibian keepers who need precise, scheduled humidity control, it replaces generic digital timers with a purpose-built solution that works in seconds — not minutes — giving you far greater control over moisture delivery in vivariums and terrariums.

Control and Programming

The ST-24 offers 10 individually programmable events (P0–P9), each with its own precise start time and misting duration. Events can be set to trigger on a specific day of the week or to repeat daily, so you can tailor humidity cycles to match the natural conditions your animals need. A backlit LCD control panel makes navigation and setup straightforward even in low light.

Flexible Scheduling in Practice

• Set a short burst of misting in the morning — for example, 25 seconds at 8:00am daily
• Follow with a longer midday or afternoon cycle — such as 2 minutes at 4:00pm every day
• Add species- or habitat-specific events on selected days only — for example, 4 minutes at 7:00pm on Wednesdays

Manual Override and Power Safety

A manual override function lets you trigger a misting cycle on demand without disrupting or resetting your programmed schedule. The ST-24 includes a rechargeable battery that retains all settings during a power failure, so your humidity regime stays intact even after an outage.

Installation and Compatibility

The ST-24 connects at low voltage directly to your existing MistKing power supply, keeping installation clean and straightforward. It is compatible with both 110V and 220V systems, making it suitable for UK setups without any modification. If you are upgrading from an older seconds timer or a generic hardware store unit, the swap is simple and quick.

For keepers running a MistKing misting system, the ST-24 Seconds Timer is the logical step up — giving you genuine precision over humidity scheduling rather than the blunt on/off control of a standard plug-in timer.
