JBL Digital Pocket Scales | 250g & 500g High Precision Portable Weighing Scale

Accurate nutrient dosing starts with accurate measurement. A 0.1g error in a small-batch powder nutrient mix or additive dose can shift your EC meaningfully, particularly in smaller reservoir volumes where concentration changes are amplified. JBL Digital Pocket Scales give you 0.1g resolution in a compact, portable unit that fits in a pocket and runs on three AAA batteries, making precise measurement practical anywhere in the grow room.

Available in 250g and 500g capacities to suit different dosing requirements. Both models feature a stainless steel weighing pan, a 5-digit LCD with green backlight, tare/zero function for container weighing, and multiple unit modes including grams, ounces, carats, and piece count. Auto shut-off preserves battery life between uses.

Key Features

• 0.1g resolution for precise small-quantity measurement. Accurate to 0.1g across the full capacity range, suitable for powder nutrients, additives, and botanical preparations.
• Available in 250g and 500g capacities. 250g suits micro-dosing and small-batch mixing. 500g covers larger additive quantities and multi-nutrient mixing sessions.
• Tare/zero function for container weighing. Zero out the weight of any container and measure net content directly, eliminating manual subtraction errors.
• Multiple unit modes. Switches between grams, ounces, carats, and piece count for flexible use across different applications.
• Stainless steel weighing pan (65 x 75mm). Easy to clean between uses and resistant to nutrient solution and botanical residue.
• Compact portable design. 135 x 80 x 24mm housing weighs 120g net. Fits in a pocket or tool kit for use anywhere in the grow room or preparation space.
• Auto shut-off and overload protection. Extends battery life and protects the load cell from damage during accidental overloading.

Frequently Bought Together

Precision scales are most useful when you're working with concentrated powder nutrients and additives. Pair with a Bluelab pH or EC meter to verify your solution after mixing, confirming that your measured dose has hit the target EC before feeding your plants. For botanical processing applications, the scales pair directly with the Decarboxylator & Oil Infuser for accurate input measurement before each infusion batch.
