Product Highlights
- With known iso sensitivity and shutter speed, the light meter provides the correct aperture value for the correct exposure.
- Built-in 120 mah lithium battery, continuous measurement for about 12 hours.
- The ah-m1 light meter from astrhori is made entirely of brass, with 0.66 inch oled display.
- Over 30° average measurement, single measurement time ≤ 0.5
- The cold shoe base can be flexibly adjusted to the desired position, so you don't have to worry about the exposure meters slipping when switching between different cameras.

Product Highlights
- 23-stop shutter speed: shutter speed increased from 12 to 23 stops, making exposure more accurate.
- 45°average metering: upgrade to convex lens for stronger light gathering effect, stepped light inlet prevents reflection. to make the metering more accurate.
- Indicator light & two dials: the current exposure status is displayed by the indicator light. the left and right dials can modify the parameters, which resemble the manual mode of camera. (tips: this product does not contain batteries, you will need to purchase cr1632 batteries separately.)
- Clicked aperture dials: upgrade to a clicked dial, which can effectively prevent accidental touching.
- Double power saving continuous metering for 60h: no operation for 10 seconds: the indicator light will automatically turn off and the it can be activated by touching the dial and metering button; no operation for 60 seconds: the light meter will turn on the sleep mode, which can be activated by clicking the metering button.

Product Highlights
- 🌱3 types of measurements: 1)dynamic measurements: as you move the meter over an area, dynamic measurements are taken every second. dynamic measurements continue to be made until you either press hold or turn the unit off. dynamic measurements are stored in an internal buffer and used to report ave (average), max (maximum), and min (minimum) dynamic measurements. 2)hold ...
- 🌱flexible performance: features a tripod socket for stable mounting during measurements, ensuring accuracy and convenience. please note: can’t leave the unit on a tripod to record average light during a period, because the unit automatically shuts off after 3 minutes when no buttons are pressed.
- 🌱ppfd measurement: measures photosynthetic photon flux density (ppfd) within a range of 0 to 5000 μmol/m²/sec. measures wavelengths within the range of 400±10nm to 700±10nm, covering the essential spectrum for photosynthesis. features a spacious screen display for effortless reading of measurements, ensuring clarity and convenience. provides max/min/avg data functionali...
- 🌱additional functions: introduces four modes, each with distinct capabilities: avec: measures ppfd every second and report the average measurement, rec: measures ppfd every second and reports the data logged, cal: zero point , and res: reset the unit and clear the log. (pls note: when you first turn the unit on, it starts in ave mode where the meter takes a pffd measure...
- 🌱 data recording and live display: enables the storage of up to 100 measured values, supporting thorough data accumulation and scrutiny. offers a live display of the most recent four recorded data points, facilitating swift monitoring and analysis. to see additional logged measurements, press the mode button until rec is displayed. after a brief delay the word rec will ...
