The device indicates with sound and light when the liquid level in the tank reaches the sensor, and helps prevent overflows and disruptions in the wastewater system. <\/p>\n<p>The alarm is designed specifically for closed tanks, septic tanks and pumping stations, and is ideal for both detached houses and holiday homes.<\/p>\n<h3><strong>Advanced and easy to install<\/strong><\/h3>\n<p>Tank-Check RF-432 GBW is installed in a 40\u201344 mm hole in the plastic lid of the tank, leaving the transmitter unit outside the lid. This ensures a reliable connection between the indoor unit and the sensor. Installation does not require any special tools, and the device is ready for use immediately after connection.  <\/p>\n<ul>\n<li>Wireless range up to 200 meters<\/li>\n<li>Battery life up to 10 years<\/li>\n<li>Finnish key flag product<\/li>\n<\/ul>\n<h3><strong>A safe and smart choice<\/strong><\/h3>\n<p>The RF-432 GBW model has two relays that allow the alarm to be forwarded to, for example, a 4G or 5G modem. This way, information about the tank being full or the connection being lost is immediately available. The renewed conductive Smartel sensor guarantees accurate and long-lasting operation in all weather conditions.  <\/p>\n<h3><strong>Specifications<\/strong><\/h3>\n<ul>\n<li>HVAC Number: 4575316<\/li>\n<li>Model: Tank-Check RF-432 GBW<\/li>\n<li>Transmitter frequency: 433.7 MHz LoRa<\/li>\n<li>Range: Unobstructed range up to 200 m<\/li>\n<li>Power supply: 3.6V AA lithium battery (lasts up to 10 years)<\/li>\n<li>Transmitter housing: Polycarbonate IP67, 65 \u00d7 115 \u00d7 40 mm<\/li>\n<li>Receiver: IP30, 80 \u00d7 120 \u00d7 38 mm<\/li>\n<li>Relays: NO\/NC, max 24V, 3A DC<\/li>\n<li>Battery and cable maintenance: no regular maintenance required<\/li>\n<li>Warranty: 24 months<\/li>\n<\/ul>\n<p><strong><a href=\"https:\/\/kauppa.vestelli.fi\/wp-content\/uploads\/sites\/4\/2025\/12\/Smartel-RF-432-Grey-Blackwater-Esite.pdf\" target=\"_blank\" rel=\"noopener\">Smartel Tank-Check RF-432 Grey- &#038; Blackwater Brochure (pdf)<\/a><\/strong><\/p>\n<\/div>\n<p>More information: <strong><a href=\"https:\/\/smartel.fi\/\">Smartel.fi<\/a><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p><strong>Delivery time<\/strong> : approx. 5\u20138 business days <\/p>\n<p><strong>Delivery method<\/strong> : Pick-up from Posti.
